Abstract: A signal processing circuit that includes a differential amplifier and an integrator. The differential amplifier receives at a first input a signal to process and at a second input an offset compensation signal provided by the integrator. The integrator includes a differential transconductance amplifier receiving an output voltage of the signal processing circuit at a first input and a reference voltage at a second input; a capacitor having a first terminal connected to the output of the transconductance amplifier and a second terminal connected to a fixed voltage; and a voltage follower receiving the voltage at the first terminal of the capacitor and providing the offset compensation signal.
