Abstract :
A monolithic realization of a switched-capacitor amplifier is reported. It has op-amp offset voltage cancellation without requiring the output to slew to ground each time the amplifier is reset. The amplifier is very insensitive to low op-amp gain. It also has clock-feedthrough cancellation. Finally, it can be used as a differential amplifier with both inputs being sampled at the same instance.
