New Advances and Possibilities in Active Circuit Design

Operational amplifiers are important building blocks for analog circuit design. Unfortunately, their limited performance such as bandwidth, slew-rate etc. leads the analog designer to search other possibilites and other building blocks. As a result, new current-mode active building blocks such as operational transconductance amplifiers (OTA), second generation current conveyors (CCII), current-feedback op- amps (CFOA), four terminal floating nullors (FTFN), differential voltage current conveyor (DVCC), differential difference current conveyor (DDCC), third-generation current- conveyor (CCIII), dual X current conveyors (DXCCII), current controlled current conveyors (CCCII) etc. received considerable attention due to their larger dynamic range and wider bandwidth. Employing these new active elements for analog design and using CMOS technology for implementation the circuit designers obtained new possibilites to solve their problems. This work covers new advances and possibilities in the related research area including application on communication, measurement and RF systems.
