Abstract :
It is important to develop circuit techniques that permit existing CMOS to implement analog circuits at power supply voltages as low as 1 V. This paper describes some of these techniques and illustrates their application in the design of a CMOS op amp operating from a 1 V power supply. This opamp uses a digital 2-/spl mu/m CMOS having threshold voltages of 0.7 to 0.8 V and demonstrates performance comparable with opamps using higher power supply voltages.
