Pseudo-Continuous Output Switched-Capacitor Amplifier for Rail-to-Rail Current Sensing Application

This paper proposes a switched-capacitor amplifier capable of generating a constant output voltage in both the phases of the clock, even in the presence of op-amp offset. Thus it has the advantage that the subsequent A/D stage can operate with at least double the data rate. The architecture is implemented in AMS 0.35um CMOS process and operates on a supply of 5V.
