Abstract :
This paper presents feedforward compensation techniques for low voltage fully differential folded cascode amplifiers and OTAs. Fully differential folded cascode cells have been fabricated and tested with different feedforward configurations in order to demonstrate and compare the usefulness of these techniques for broadbanding the gain-bandwidth product of low voltage, low power CMOS amplifiers and for providing high quality low voltage CMOS OTA integrators
