Patent ID: 7224216

Claim:
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 coupled in parallel to each other and 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 provided by a summer that generates a sum of the partial gain amounts of the at least two chopping amplifier stages and wherein an output signal of the chopping amplifier is responsive to the summer; and wherein one of the at least two chopping amplifier stages comprises an input chopping switch that can either be in a non-inverted connected state or an inverted connected state, a first pain stage having an input coupled to the input chopping switch, an output chopping switch coupled to an output of the first pain stage and wherein the input chopping switch repeatedly changes states at a first set of transition time; wherein another of the at least two chopping amplifier stages comprises another input chopping switch that can either be in a non-inverted connected state or an inverted connected state, a second gain stage having an input coupled to the another input chopping switch, another output chopping switch coupled to an output of the second pain stage and wherein the another input chopping switch repeatedly changes states at a second set of transition times; and wherein the first set of transition times is non-overlapping with and different from the second set of transition times.
