CMOS Operational Amplifiers for Switched Capacitor Filter Application

This paper studies the design of a CMOS operational amplifier for the switched capacitor filter by computer simulation, and presents the results of measurement. The operational amplifier composed of two stages is fabricated in the CMOS digital process. The DC voltage gain of the operational amplifier is 66dB, and the unity gain bandwidth is 833kHz. These results satisfy the performance requirmance requirements for the operational amplifier of the switched capacitor filter.
