FIELD: electronics.
SUBSTANCE: invention can be used in microelectronic signal processing systems. In a CMOS amplifier, the input amplifier has two pairs of static calibration inputs connected to the inputs of the output cross-switches, and two pairs of dynamic calibration inputs connected to the outputs of the output cross-switches, and two pairs of static calibration inputs connected to two pairs of static calibration current source outputs and two pairs of dynamic calibration inputs are connected to two pairs of dynamic calibration current source outputs, while currents opposite in direction are set to the calibration inputs in each pair and opposite currents are set to the calibration inputs of each pair.
EFFECT: reduction in the dynamic offset of an amplifier with chopper stabilization, increasing its stability in the range of operating temperatures and supply voltages.
