This paper presents a methodology to create a Simultaneous Switching Noise (SSN) predictive SPICE model for a 32-bit microcontroller. Here, the purpose is to predict the noise interference generated by switching IOs and establish new design/layout rules for the next product generation in order to reduce these interferences. This model achieves an accurate correlation between measurements done on a 32-bit MCU and Eldo simulations. Then, features are defined in order to build this accurate model. Having this, a deeper research work can be done only by simulation.

One big challenge of the emerging atomic precision advanced manufacturing (APAM) technology for microelectronics application is to realize APAM devices that operate at room temperature (RT). We demonstrate that semiclassical technology computer aided design (TCAD) device simulation tool can be employed to understand current leakage and improve APAM device design for RT operation. To establish the applicability of semiclassical simulation, we first show that a semiclassical impurity scattering model with the Fermi-Dirac statistics can explain the very low mobility in APAM devices quite well; we also show semiclassical TCAD reproduces measured sheet resistances when proper mobility values are used. We then apply semiclassical TCAD to simulate current leakage in realistic APAM wires. With insights from modeling, we were able to improve device design, fabricate Hall bars, and demonstrate RT operation for the very first time.

This article proposes a very compact planer open-loop bandpass filter (BPF) with asymmetric frequency response and covering the 2.5 to 2.6 GHz and 3.6 to 3.7 GHz spectrum for 4G and 5G applications, respectively. The microstrip BPF employs four open-loop ring resonators with 50 Omega tapped lines for input and output ports. To achieve sharper cut-off frequencies, one infinite and three finite transmission zeros are successfully generated on the upper and lower edges of the 4G and 5G passbands. The utilization of the planer four-section resonators not only reduces the size of the structure, but also provides either positive or negative cross-coupling. The cross-coupling coefficients between the resonators are optimized to resonate at the required frequency with proper bandwidth. The reported BPF is designed and optimized using CST software, and is implemented on a Rogers RO3010 substrate with a relative dielectric constant of 10.2 and a very compact size of 11x9x1.27 mm(3). Good agreement is achieved between the simulated and measured results.

This paper explores a new integrated-circuit architecture of an analog, active, tunable and selectively fractional or integer-order PID controller using operational amplifiers. Controller's major parameters are tuned via appropriate DC currents to the desired values. The proposed architecture is validated in a case study of a DC motor control and it can be used as a building block in industrial and commercial control systems. Circuit and physical design (layout) have been done in TSMC 90nm CMOS process. Extensive circuit and post-layout simulation are carried out using the Cadence IC design.

Moisture is an important factor to reliability, functionality and durability of electronic devices. Nowadays, modelling tools have become an integral part of electronics design, because they are less expensive for searching the optimal design of moisture control. CFD and FEM are very time consuming due to their computational effort, therefore it is desirable to have a method such as well-known Resistor-Capacitor (RC) approach which is faster and has less spatial resolution. The paper concerns the development of an in-house code using the RC approach for simulating coupled heat and moisture transport inside electronic enclosure under non-isothermal conditions. Thereafter, the simulations results were compared with corresponding experiments in order to validate the developed code. Based on comparison with experiments, a new configuration RC model was developed for a more accurate humidity prediction. In general, new RC model had the adsorption and desorption mechanisms included as a lumped capacitance for describing the surface of a wall on its both sides. Such modification improved the agreement with experiments.

A Pulse Compression procedure for power inductors modeling up to moderate non-linearity

Several studies have proved that the use of Ferrite Core (FC) power inductors operating in moderate saturation allows volume and weight of Switch-Mode Power Supplies (SMPSs) to be reduced. Thus, a reliable analysis of non-linear FC inductors operating in moderate saturation is fundamental for the design of high-power-density SMPSs. This paper suggests the application of a Pulse Compression procedure for the Hammerstein model identification of the inductance versus current characteristic of FC inductors. The proposed approach allows a reliable model of FC inductors to be obtained up to moderate saturation non-linearity. Several simulations in cases of practical interest are presented, with comparisons to an established literature behavioral model and its Taylor and Pade numerical approximations.

The memristor is a passive two-terminal electrical device where its conductance is accurately modulated either by the charge or the flux flowing through it. In this paper, we implement a simple and flexible Verilog-A memristor model in order to perform synaptic functions, including both long-term potentiation LTP and long-term depression LTD, to subsequently validate the Hebbian learning algorithm (STDP). Our simulation results reveal the I-V characteristic of a Ta 2 O 5 -based memristive device. We prove that the Verilog-A model is able to reproduce the conductance change in the STDP learning method. Therefore, the use of memristors as synapses in neuromorphic circuits may potentially provide high connectivity and high-density area for efficient computation.

Virtual prototyping is the way forward to shorten development cycles and deliver optimized design solutions for semiconductor components and electronic modules. It allows us to make virtual experiments for devices that have never been built before. We can predict safe operating areas and on the other hand identify critical use conditions. Key requirement for virtual prototyping is an efficient and accurate simulation model that does consider multiple physical domains (e.g. thermal, electrical, mechanical) along with complex 3-D structures. The focus of the current paper is to present an efficient simulation flow for prediction of three-dimensional temperature fields at transient operating conditions with multiple heat sources and associated thermal cross talk at component and system levels. In what follows, we will demonstrate the virtual assembly of an electronic control unit (ECU) and its transient thermal simulation in time domain. We will decompose the unit into its major components for which fast mathematical models will be derived by means of model order reduction techniques. We will then create a reduced mathematical model of the entire ECU by simply interconnecting all component models at predetermined I/Os. We will demonstrate a stimulus-response analysis of the interconnected system and a subsequent result expansion path for 3-D visualization of temperature fields. Finally, we will compare simulation results of the reduced system model with the corresponding full-scale finite element model.

In order to design a high-power ICP (Inductive Coupled Plasma) RF power supply and verify its correctness, a class E power amplifier circuit and an automatic impedance matching circuit are built in Simulink. The analysis of the results shows that the Class E power amplifier built in this paper can meet the design requirements, and the impedance matching algorithm can achieve the maximum power output of impedance matching by adjusting the value of the matching network components. This simulation circuit based on Simulink simulates the load changes during ICP operation to verify the correctness of the power amplifier design and matching algorithm.
