Abstract
This paper presents the design of two stage operational trans-conductance amplifier (OTA) with feed-forward compensation scheme. Without using Miller capacitance, proposed OTA presents a high gain and large bandwidth without compromising good phase margin. The prototype circuit is designed using TSMC 45nm process. Post layout simulation results show a 60.5 dB of gain, 546.6 MHz unity-gain frequency, and 73° phase margin while driving 8pF capacitive load and consuming 3.4 mW power from 1 V power supply.
