Abstract: A low voltage, low power bulk driven Operational Transconductance Amplifier (OTA) is designed in 180 nm CMOS Technology. The OTA employs feed-forward compensation achieving open loop DC gain of 44.05 dB, 3 dB bandwidth of 408 kHz, Unity Gain Bandwidth (UGB) of 9.07 MHz. OTA is stable with phase margin of 45� and a gain margin of 66 dB for a pure capacitive load of 1 pF. OTA operates on 0.5 V supply consuming a power of 30 ?W. � 2011 IEEE.
