As digital CMOS processes continue to advance, the size and power consumption of digital circuitry decreases dramatically. At the same time, lower supply voltages make the design of high resolution analog-to-digital converters increasingly difficult. Therefore, there is great motivation to implement some signal processing in the analog domain in order to reduce A/D converter resolution. Analog ...

Renewable energy sources can be used for electric power generation to supply specific devices in distributed systems such as smart grids. Hydrogen fuel cells have proven to be an effective solution to produce electrical energy with fairly good efficiency and minimum environmental pollution. A single-stage solution to interconnect a fuel cell with a low-voltage distribution system is proposed in...

This paper presents a new general purpose reconfigurable technology platform for embedded system design called Kress ALU Array III (KrAA-III), which is a novel field programmable ALU array (FPAA). FPAAs can be structurally programmed to resemble a complex operator used by an application, providing high computation power by massive pipelining. While embedded accelerator design with traditional F...

This article presents an integrated current mode configurable analog block (CAB) system for field-programmable array (FPAA). The proposed architecture is based on the complementary metal-oxide semiconductor (CMOS) transistor level design where MOSFET transistors operating in saturation region are adopted. CAB designed to implement six of widely used operations processing systems: addition, subt...

− This paper describes the design of a 12-bit 80MS/s Digital-to-Analog converter implemented in a 0.13μm CMOS logic technology. The design has been computer-aided by a developed toolbox for the simulation and verification of Nyquist-Rate Analog-to-Digital and Digital-to-Analog converters in MATLAB. The converter is segmented in an unary current-cell matrix for 8 MSB's and a binary-weighted arra...

Several techniques are available for implementing DC-DC converters using digital controllers Among these FPGA (Field Programmable Gate Array) based implementation provides various advantages in terms of speed, flexibility, low power usage, reduced equipment sizing and massive parallelism. The traditional methods allow fault diagnosis only after the final implementation which leads to extra cost...

In this work the electronics for a highest resolution heterodyne interferometer is presented. It comprises an analog front-end, a high speed dual channel analog-to-digital converter and a field programmable gate array for high speed, low latency signal processing. The gate array contains a system on chip (formulated in a hardware description language), consisting of the main processing block (l...
