The design of acoustic resonator is critical for the sensitivity of photoacoustic (PA) gas detection. In this paper, a LC Circuit model is built for the simulation of ID acoustic resonator with considerations of some nonideal factors such as the boundary layers in detail. The model is verified by the device and the corresponding experimental data. As an application of the model, a ID acoustic resonator for CO photoacoustic spectroscopy is studied. The effects of the structrual parameters, quality factor and resonant frequency on the performance of the device are theoretically analyzed. It's worthy noted that for the first time we point out the effect of the ambient temperature. © 2006 IEEE.

In MEMS realization of high frequency ultrasonic array transducer, electrical impedance matching may become difficult for the reason of the miniaturization of the piezo-array elements. In this study, the electrical impedance of the array elements is estimated first by using KLM model, and then calculated by using finite elements method(FEM), in the case of a Li Nb O3 based30 MHz array transducer. The impedance frequency behavior is related both to the eigen-resonance modes and the electrode driven modes with the free mechanical boundary condition of the element and to the coupling of these modes to the array structure when the element being integrated as the transducer. The array transducer properties and performances such as lateral modes,crosstalk, sensibility and bandwidth, field radiation,focusing/steering are also simulated and analyzed.

In this work, we review our recent studies on several novel devices built on silicon-on-insulator (SOI) substrates. The sharp-switching Z2-FET, based on a feedback mechanism, has been demonstrated as suitable for many applications. The PISD, capable of in-situ photoelectron sensing, has been used as a one-transistor active pixel sensor (1T-APS). Furthermore, an SOI/MoS2 heterojunction FET has been demonstrated as both a photodetector with a dynamic response spectrum and as a novel one-transistor wavelength detector (1T-WD) with an output signal sensitive to the variation of wavelength rather than intensity. © 2020 IEEE.

An automated test framework for SRAM-based FPGA is presented. With the framework, test configurations of different categories can be partially or completely generated, and the tests be running using the generated configurations. Data driven design provides the test framework the flexibility of change the user interface and the command line arguments via software configuration files, without modifying the source code of the framework. Experimental results shows that the test framework handles the complicate test flow efficiently, and release the test engineer from the tedious testing work. © 2015 IEEE.

We propose two tiers of modiications to FPGA logic cell architecture to deliver a variety of performance and utilization beneits with only minor area overheads. In the irst tier, we augment existing commercial logic cell datapaths with a 6-input XOR gate in order to improve the expressiveness of each element, while maintaining backward compatibility. This new architecture is vendor-agnostic, and we refer to it as LUXOR. We also consider a secondary tier of vendor-speciic modiications to both Xilinx and Intel FPGAs, which we refer to as X-LUXOR+ and I-LUXOR+ respectively. We demonstrate that compressor tree synthesis using generalized parallel counters (GPCs) is further improved with the proposed modiications. Using both the Intel adaptive logic module and the Xilinx slice at the 65nm technology node for a comparative study, it is shown that the silicon area overhead is less than 0.5% for LUXOR and 5-6% for LUXOR+, while the delay increments are 1-6% and 3-9% respectively. We demonstrate that LUXOR can deliver an average reduction of 13-19% in logic utilization on micro-benchmarks from a variety of *** benchmarks beneit the most with an average reduction of 37-47% in logic utilization, which is due to the highly-eicient mapping of the XnorPopcount operation on our proposed LUXOR+ logic cells. © 2020 Association for Computing Machinery.

A novel resistive negative feedback wideband low-noise amplifier (LNA) with feedforward noise and distortion cancelation is presented in this paper. In comparison to conventional resistive negative feedback LNA's the proposed LNA circuit shows improved performance parameters including voltage gain, noise figure (NF) and input-referred third-order intercept point (IIP3). Especially for wideband LNA design's in deep sub-micrometer CMOS technologies, the proposed noise cancelation is efficient. A testchip is fabricated in 65nm CMOS. Measurement results show an LNA performance of 24dB voltage gain, 2dB NF, -5.5dBm IIP3 and S11

In this work, we explored an efficient automatic layout routing algorithm for connecting the power and ground pins in analog integrated circuits. A rectilinear minimal spanning tree (RMST) algorithm for two sets of pins is developed, in which minimal spanning tree is used to form the initial connections between pins. The obstacle-avoiding maze routing algorithm is used to break and reconnect the power and ground nets to avoid any short circuit. The genetic algorithm (GA) is further introduced to optimize the total connection wirelength. We also expanding the wire width to avoid electromigration and IR-drop. © 2023 IEEE.
