Abstract :
This work describes a simple topology for implementing a low voltage rail-to-rail CMOS Miller OTA with differential pair using bulk driven and DC shifters. Since the transistors work on weak inversion, the topology requires a 600 mV power supply and consumes only 420 nW on the 0.35 μm TSMC CMOS process. The voltage swing and the frequency response are almost independent of the power supply voltage that can change from 600 mV to 3.3 V (limit of this technology).
