CMOS cascode inverters
A low voltage operating fully-differential CMOS OTA construction, which uses dual-input CMOS cascode inverters, is proposed. The OTA is a two-stage configuration with dual-input CMOS cascode inverters at the input stage, and traditional CMOS inverters in the output stage, with a common-mode feedback path from the output terminals to one of the input terminals of cascode inverters. In order to effectively reduce its threshold voltages by bulk bias technique, the OTA has been designed and fabricated by using a 0.15 μm triple-well CMOS process. The OTA successfully operated from 1-V power supply, with 59 dB of differential voltage gain, 80.9 dB of CMRR and 25 MHz of unity gain frequency, at 60 μA of current consumption.
