Abstract
Examples of a digital transceiver, a switched-capacitor sampling mixer, and an N-stage switched-capacitor amplifier are generally described herein. The digital transceiver may include a plurality of switched-capacitor sampling mixers and a plurality of N-stage switched-capacitor amplifiers. Each mixer samples a received differential RF signal. The pair of N-stage switched-capacitor amplifiers operates as charge redistribution amplifiers. Each N-stage switched-capacitor amplifier provides a near-constant capacitive load for one of the mixers.
