Abstract :
This work describes a simple topology to implement a low voltage rail-to-rail CMOS Miller OTA with differential pair using DC shifters and bulk driven inputs. The transistors work on weak inversion and 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 ranging from 600 mV to 3.3 V.
