Abstract:
The present disclosure is directed to a switched capacitor amplifier that includes a switched capacitor network and a complementary push-pull amplifier. The switched capacitor amplifier of the present disclosure can provide a larger fraction of the charge provided by a power supply and flowing through the amplifier to a capacitive load at the output of the amplifier compared to switched capacitor amplifiers that use single-ended class-A amplifiers. The switched capacitor amplifier of the present disclosure can be used in a converter stage of a pipelined analog-to-digital converter (ADC) to improve the ADC's power efficiency and/or bandwidth. It can be further generalized to be used in other applications other than pipelined ADCs.
