ETRI Journal, Volume 29, Number 1, February 2007 A new low-voltage CMOS interface circuit with digital output for piezo-resistive transducer is proposed. An input current sensing configuration is used to detect change in piezo-resistance due to applied pressure and to allow lowvoltage circuit operation. A simple 1-bit first-order deltasigma modulator is used to produce an output digital bitstre...

This work presents the implementation of multidimensional membership functions by means of an analogue Neuro-Fuzzy circuit realized in 0.8μm CMOS technology. The adopted circuit configuration is discussed and preliminary measurements of an integrated circuit prototype are reported. 1 Circuit implementation The fuzzy system model used in this work is based on the so-called fuzzy if-then rules [1...

We developed a content delivery system using a partially reconfigurable FPGA to securely distribute digital content on the Internet. With partial reconfigurability of a Xilinx Virtex-II Pro FPGA, the system provides an innovative single-chip solution for protecting digital content. In the system, a partial circuit must be downloaded from a server to the client terminal to play content. Content ...

Numerous circuit models have been proposed to represent the electrode–electrolyte interface (EEI) impedance and bulk medium of conducting media. Following a review, two suitable are constructed behavior conduction in electrolytes soils, respectively. Both incorporate constant phase element parallel with an apparent Faradaic resistance, which is found reproduce EEI accurately. For electrolyte mo...

this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...

In this paper a new optimization function for increasing the flux weakening range and output torque value of segmented interior permanent magnet synchronous motor (SIPMSM) is presented. In proposed objective function normalized characteristic current and saliency ratio are considered as two optimization variables during optimization process. The focus of this paper is rotor structure design suc...

A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...
