A Universal Amplifier Module (UAM) in 0.18 µm CMOS (CMOSP18/TSMC) Technology With Some Applications in Analog Signal Processing

摘要

The amplifiers such as operational amplifier, operational transconductance amplifier, operational transresistance amplifier, current conveyor etc. are the basic building blocks in analog circuits and systems. These important basic amplifiers find wide spread applications in the integration of several electronic systems. However, different analog devices are preferred for different systems. It is difficult to use a single type of device to cater for the needs of different systems with diverse input output impedance environments.ududIn this thesis work, a Universal Amplifier Module (UAM) is designed and implemented in a modern 0.18µm CMOS (CMOSP18/TSMC) technology and its applications toward realization of second order voltage and current – mode filters are reported. Concepts of network transposition and nullor equivalent of ideal active devices are utilized to realize both voltage and current – mode filters using the same UAM module which is able to provide all the voltage and current mode operations (such as, OP-AMP with VCVS, OTA with VCCS, OTRA with CCVS, and CCCS). ud
