摘要：The Operational Transconductance Amplifier is a basic building blocks found in many analog circuits such as dataconverter’s (ADC& DAC) and Gm-c filters. The OTA is an amplifier whose differential input voltage produces an output current .Thus ,it isa voltage controlled current source(VCCS) whereas the Op-amp are voltage controlled voltage source(VCVS). There is usually an additionalinput for a current to control the amplifier’s transconductance. The paper represents the different topology of CMOS OTA is described andat last comparison between different configuration is given
