Abstract:
1. A method of chopping an input signal by a chopping amplifier, comprising: segmenting, by a chopping amplifier, a chopping operation of an input signal across at least two chopping amplifier stages, wherein the at least two chopping amplifier stages are responsive to a master controller and wherein each of the at least two chopping, amplifier stages contributes a partial gain amount to an overall gain of the chopping amplifier and wherein the overall gain is a sum of the partial gain amounts of the at least two chopping amplifier stages; and wherein during non-switch transition periods, all of the at least two chopping amplifier stages are active and chopping; and wherein during a switch transition period, one of the at least two chopping amplifier stages is disconnected while all remaining ones of the at least two chopping amplifier stages are chopping.
