摘要：
The Operational Transconductance Amplifier is an amplifier which uses the differential input voltages and generates the output current. Therefore, it is a voltage controlled current source. OTA is an important block in the design of analog filters. The continuous scaling down of the transistor size and reduction in power supply has added stringent design constraints in analog architecture. Here we design a bulk driven OTA with 0.4 V supply in 180nm CMOS technology using Cadence Virtuoso. The performance parameters such as gain, CMRR, Unity Gain Bandwidth, power, DC sweep error, Total Harmonic Distortion, output impedance and transconductance are analyzed. Further the Gm-C filter and Bi-Quad filter are designed using the proposed OTA.
