This paper describes a simple, inexpensive transimpedance amplifier (TIA) suitable to convert the fast current pulses delivered by photomultiplier tube of night airglow photometer into the corresponding voltage. Design criteria for the transimpedance amplifier are carefully selected to include low input bias current, offset voltage and noise. The operation of the transimpedance amplifier and th...

In this paper, reduced power consumption, low-noise CMOS amplifier using chopper technique is designed, chopper-equalized amplifier had been used as a front end of a voltage-to-frequency converter instrument which performs pretty well, and they were meeting just about every specification, but they had a problem with undesired and unpleasant little offset shifts and jumps. Trying to solve this p...

Mann, David William: 90nm CMOS Driver Amplifier for WCDMA Mobile Applications (Under the direction of Dr. Kevin Gard.) Integration is driving today’s cellular phone industry to create single chip cellphone systems. With the integration of Radio Frequency Transmitters into CMOS technology, robust circuits are needed that can scale with new technologies. This thesis explores the challenges of des...

In this paper, we develop a target detection algorithm based on a supervised learning technique that maximizes the margin between two classes, i.e., the target class and the non-target class. Specifically, our target detection algorithm consists of 1) image differencing, 2) maximum-margin classifier, and 3) diversity combining. The image differencing is to enhance and highlight the targets so t...

This paper summarizes and discusses findings on compatibility of the forthcoming DRM mode E into classical VHF FM sound broadcasting. The results are based on theoretical considerations, lab measurements, field trials and radio network planning exercises. In addition, the status of the ongoing work towards a comprehensive DRM mode E coverage study including first results hereof are given.

The comparator is designed in pipelined ADC. FINFET is the technology which performs the dual gate MOSFET. This thesis focuses on the high-speed design of pipelined ADC. In the meanwhile, we try to minimize the power dissipation as well. In this thesis, A semidigital Gm-based amplifier is proposed for a low-power pipelined analog-to-digital converter (ADC )in HSPICE .And also we compare the pow...
