Abstract

Abstract- This paper presents design concept of Small-Gm Operational Tran conductance Amplifier (OTA). The 0.18m CMOS process is used for Design and Simulation of this OTA. This OTA having a bias voltage 1.8 with supply voltage 1.8 V. The design and Simulation of this OTA is done using CADENCE Spectere environment with UMC 0.18m technology file. The Simulation results of this OTA shows that the open loop gain of about 76 dB which having Unity Gain Frequency of 90.25 MHz This OTA is having CMRR of 91dB and PSRR of 80dB. This OTA having power dissipation of 0.74 mW and Slew Rate 2.344 V/?sec.
