Frequency compensated, multistage amplifier design, includes inverting chopper modulator operating in phase with separate Miller feedback capacitors

摘要

A modulator (MOD1) is connected to input- and output amplifier stages (V2, V1), all in series. The modulator chops the signal into first and second inverted phases. Miller compensation capacities (C1, C2) are connected in alternation between the output and input of the output amplifier stage (V1), in phase with the chopping cycle. An independent claim is included for the corresponding method of operation.
