SAMPLED-DATA RECEIVER WITH CHOPPER STABILIZATION
This abstract first appeared for US patent application 20250105808 titled 'SAMPLED-DATA RECEIVER WITH CHOPPER STABILIZATION
Original Abstract Submitted
embodiments herein provide various apparatuses and techniques to reduce flicker noise and voltage offset from the buffers and/or amplifiers while avoiding additional alias components in a sampled-data receiver with chopper stabilization. additionally, a direct-conversion baseband chain may be improved by disposing alternating current (ac) coupling circuits between chopper circuits in the transmitter or receiver chain to enable selection of a distinct common-mode level at each stage of the direct-conversion chain, while reducing or eliminating signal loss at direct current (dc) frequencies.
