A cascade of amplifier stages has a differential input and a differential output. The cascade of amplifier stages includes at least one differential amplifier circuit including first and second transistors, at least one of the first and second transistors having a control terminal and a body terminal. A mismatch between the first and second transistors generates an input offset. A feedback network couples the differential output to the body terminal in order to cancel the input offset. The feedback network includes a low-pass filter and a differential amplifier stage.
