Many CMOS image sensors now use columnparallel readout structure with single slope ADCs. Ramp generator in the ADCs is a critical building block since the performance of the ADCs depends a lot on the accuracy of the ramp signal. In this paper, we present several ramp generator architectures and compare their performance in terms of resolution, area, noise and reliability.

In this paper, an FPGA-based digital modulation signal generator with fading channel effect is presented for basic experimental usage. Instead of using off-the-shelf but costly instruments to test various communication systems, this FPGA-based signal generator is more cost-effective. We use Altera Stratix EP1S25 DSP development board as the hardware platform, which can be rapidly and flexibly r...

An autonomous control methodology is proposed for locomotive agents to have lifelike personified behaviors. The control introduces a pattern generator that is constructed by connecting oscillators composed of mutually inhibited neurons. The rhythmic signal of the pattern generator drives a proportional derivative controller that determines the legs joint angles of a locomotive agent, and the si...

Controlling chaos signal patterns at 12GHz was demonstrated on the resonant tunneling chaos generator circuit. This was made possible by implementing the reset switch, which resets the circuit to various initial conditions periodically. The reset period was set so short that the initial condition errors can not grow significantly. Thus the circuit repeated identical signal patterns, and they ca...

We introduce the stripmap mode test of X-band AutoSAR (automobile synthetic aperture radar) prototype in this paper. We design and develop a power amplifier, a signal demodulator, and use Matlab for post-processing. The transmitter of this prototype, however composes measurement instruments, an Arbitrary Waveform Generator (N8241A, Keysight) for chirp generation and a Vector Signal Generator (E...

The objective of this study was to describe the development of vibrating insoles. Insoles, providing a subsensory mechanical noise signal to the plantar side of the feet, may improve balance in healthy young and older people and in patients with stroke or diabetic neuropathy. This study describes the requirements for the tactors, (tactile actuators) insole material and noise generator. A search...

New adaptive scheme for signal parameter measurement for generator monitoring and protection is presented. The algorithm is based on the orthogonal components of currents and voltages obtained with adaptive orthogonal filters. The filter data window length and coefficients are adapted according to coarsely estimated signal frequency. As a result, the measurements can be performed with high accu...

Application Specific Integrated Circuits (ASICs) and Digital Signal Processors are generally used for implementing digital filters. Now days in the advances in technology leads to use of field programmable Gate Array (FPGA) for the implementation of Digital Filters. The Present paper deals with Design and implementation of digital IIR Butterworth filter using Xilinx System Generator. The Quanti...

A Fuzzy Power System Stabiliser (FPSS) design using discrete inputs is presented. The FPSS basically utilises only one measurable plant signal as input, namely, the generator speed. The speed signal is discretised resulting in three inputs to the FPSS. A simplified power system represented by a single generator transmitting power to the infinite bus is considered for investigations. The system ...
