This paper presents the designing and performance analysis of Operational Transconductance Amplifier using the 45nm Technology from mosis foundry. This transconductance design is having a biasing current of 5?A with supply voltage of ±1 V. The open loop gain obtained from this design is about 66.5 dB with UGB of 22 MHz is obtained from this design. This OTA design has a CMRR value of 74 dB and PSRR of 70 dB with Power dissipation of 68 ?W and Slew Rate 5 V/?sec. Simulation is done using UMC 45nm technology file.
