Abstract
A differential amplifier comprises a first amplifier (A) with a signal input (Inp) and a signal output (Out) that is fed back to a first feedback input (In) of the first amplifier (A) and is also connected to a first output (outp) of the differential amplifier. Furthermore, a buffer circuit (Buff) is connected to the first output (outp). A nonlinear resistor circuit (Rnl, Rnl) is coupled via a first output node (Vmid) with the first output (outp) and via a second output node (Vmid) with the buffer circuit (Buff).
