1-V Power Supply CMOS Cascode Amplifier
We design a folded cascode operational transconductance amplifier in a standard CMOS process, which has a measured 69-dB DC gain, a 2-MHz bandwidth, and compatible input- and output voltage levels at a 1-V power supply. This is done by a novel, current driven bulk (CDB) technique, which reduces the MOST threshold voltage by forcing a constant current though the transistor bulk terminal.
We also look at limitations and improvements of this CDB technique.
