Abstract:
Aspects of this disclosure relate to an amplifier with at least two chopper amplifier channels in parallel between a shared input and differential nodes. The amplifier can multiplex outputs of the chopper amplifier channels to provide the output of one or more chopper amplifier channels to the differential nodes at a time. In certain embodiments, this can mask dynamic settling errors.
