Electrochemotherapy (ECT) is a clinical procedure for the local treatment of solid tumors, which combines the application of pulsed electric fields (PEFs) and chemotherapeutic drugs, by exploiting the PEF-induced membrane permeabilization (electroporation, EP). The ESOPE pulsing protocol (8 pulses with 100 mu s duration and 1 kV/cm electric field strength, given at 1 Hz or 5 kHz as repetition rate) is the only protocol approved for application on human patients and is currently used in the clinical practice. Moving from an experimental study comparing the efficacy of ESOPE to that of modified PEF protocol with lower electric field intensity and higher pulse number, in this paper an electrophysiological model is used to provide theoretical support to the experimental results. The pore density and the transmembrane voltage time behavior at the upper pole of a single spherical cell are considered, in order to assess the EP effect of the applied pulse train, considered as boundary condition in the field based solution of the problem. The simulation results highlight that, 40 pulses 750 V/cm is a good candidate as ESOPE equivalent protocol.

Of interest is the possibility of implementing many-valued logic systems using traditional CMOS tecluiologies. We considered an example of the implementation of three-valued logic elements based on symmetric 3vL, logic using the values {-,0,+}, {-1.0, +1}, {1,0,1}, {i, 0, 1} etc. From the totality of obtained results, it can be assumed that ternary CMOS logic can be fully implemented according to norms of 28-180 mu with minimal changes for design rules.

Millimeter-wave circuits in current nanometric technologies are especially sensitive to process variations, which can seriously degrade the device behavior and reduce fabrication yield. To tackle this issue, conservative designs and large design margins are widely used solutions. Another approach consists in introducing variable elements, also called tuning knobs, to allow post-fabrication tuning. One-shot statistical calibration techniques take advantage of advanced machine learning regression tools to propose a set of tuning knobs values that enhance the circuit performance based on simple measurements. Training the regression models require a huge amount of data covering the device performances, the effect of the tuning knobs and the simple measurements that guide the regression. In this work, we propose an efficient method for generating such a data set that reduces noticeably the size of the required training set for an accurate calibration.

In stretchable electronics, meander designs are often used for the conducting traces. This geometry of the copper traces, that are much stiffer than the polymer substrates, allows for better stretchability. In order to be able to assess the meander reliability in a quantitative way, the possibilities and obstacles of finite element model based lifetime prediction have been investigated. Therefore, a parametric FE model of a test structure including a copper meander track has been set up and evaluated for the resulting mechanical stresses and strains under tensile loads. The comparison to experiments allowed to create a lifetime model and then perform a virtual optimization to find the best design.

This work presents a novel statistical-based general compact model for 7nm technology node devices like FinFETs. Unlike conventional compact model based on less accurate elements including one-dimensional Poisson equation for three-dimensional devices and analytical equations for short channel effects, quantum effects and other physical effects, the general compact model combining few TCAD calibrated compact models with statistical methods can eliminate the tedious physical derivations. The general compact model has the advantages of high accuracy, strong scaling capability, good robustness and excellent transfer capability. It is demonstrated that the performance of 6T SRAM and RC control ESD power clamp through the trade-off between two key design knobs of FinFET can be improved extremely with implementation of the newly proposed general compact model. This framework is also suitable for path-finding researches on 5nm node gate-all-around devices, like nanowire FETs, nanosheet FETs and beyond.

The functionality verification of a mixed-signal sys-tem on chip requires the model for RF front-end with high simulation efficiency. The pure passband model cannot meet this requirement when a long system time simulation is run. The equivalent baseband model is an alternative. In this work, a new baseband modeling method based on a self-defined signal type is realized on the platform of SystemC/-AMS. This method can more accurately describe the block nonlinearity than the traditional equivalent baseband model. For the application in the design of a global navigation satellite system (GNSS) receiver front-end, the baseband simulation based on this method has much faster simulation speed than passband simulation.

The design of decimation filters for Delta Sigma Converters is a rarely discussed topic though these filters are necessary for ?S modulator ADCs. In this work, we present a low-power decimation filter for a neural recording front-end. We show the applied design criteria and compare different filter structures to find the most efficient implementation. The decimation filter has been implemented and simulated in a 180 nm HV-CMOS process. It achieves a low power consumption of 6.4 µW at a supply voltage of 1.2 V. The filter has a 13 bit output running at a sampling rate of 22 kHz and requires an area of 460 µm x 210 µm. The input signal’s SNDR degradation due to the filter is less than 2 dB. © VDE VERLAG GMBH.

In this paper, the design, modeling, and characterization of a display compatible pMUT platform are presented. A FEM model is built using COMSOL Multiphysics for evaluating the frequency response, mechanical performance, acoustic pressure, and driving efficiency of our pMUT device across all vibration modes of circular plates. In parallel with it, a first mode analytical model has been developed including electrical, mechanical, and acoustic domains to provide fast estimation for future design. A laser Doppler vibrometer is used to measure the frequency response, displacement, velocity as well as mode shapes of pMUTs with different designs in air. The measured resonance frequency of first mode range from 121.5kHz to 1.1MHz with radius from 500 mu m to 120 mu m and fits the prediction of FEM and analytical models. A standard reference microphone is used to measure the acoustic pressure of pMUT inside its frequency range (<125 kHz). The measured acoustic pressure on transverse axis of a 500 mu m radius pMUT also fits the values from analytical model on acoustic domain.

Information processing for mechatronic systems

ROBOTICS AND AUTONOMOUS SYSTEMS 1996年第2期19卷 117-134页

作者： Isermann, R Institute of Automatic Control Laboratory for Control Engineering and Process Automation Technical University of Darmstadt Landgraf-Georg-Str. 4 D-64283 Darmstadt Germany

The integration of mechanical systems and microelectronics opens many new possibilities for process design and automatic functions. After discussing the mutual interrelations between mechanical and electronic design the different ways of integration within mechatronic systems and the resulting properties are described. The information processing can be organized in multilevels, ranging from low-level control, through supervision to general process management. In connection with knowledge bases and inference mechanisms intelligent control systems result. The design of control systems for mechanical systems is described, from modeling, identification to adaptive control for nonlinear systems. This is followed by solving supervision tasks with fault diagnosis. Then design tools for mechatronic systems are considered and examples of applications are given, like intelligent control of an electromechanical throttle actuator and force and torque reconstruction for a robot.

The coil geometry and improvement of misalignment tolerance is a key challenge for the optimization of wireless power transfer (WPT) systems. In this paper a double-D shaped coil geometry is modeled and optimized for a bidirectional wireless power transfer system for electrical vehicles (EVs) with vehicle to grid (V2G) capabilities. With the new proposed winding configuration, the magnetic coupling is less sensitive to parking misalignments, which is useful for a highly efficient battery charging system. Further efforts to reduce the amount of ferrite material helps to lower the weight and cost of the system without affecting the performance. In order to verify the effect of the winding geometry experimentally, a 3.6 kW hardware prototype was built. © VDE VERLAG GMBH.
