Abstract
A switched capacitor network includes a switch device alternatingly charging two first capacitors having the same capacitance from a signal voltage source with polarities being opposite relative to a ground potential and then discharging each of the two first capacitors through the input circuit of a respective differential amplifier. The switch device alternatingly charges two second capacitors having the same capacitance in phase opposition with one another from a reference voltage source with the same polarities relative to the ground potential and then discharges each of the two second capacitors through the input circuit of a respective one of the differential amplifiers, in synchronism with the charging and discharging of the two first capacitors. The switch device charges each of two third capacitors having the same capacitance as the second capacitors in phase opposition with a respective corresponding one of the second capacitors from the reference voltage source with the same polarities relative to the ground potential and then discharges each of the two third capacitors through the input circuit of a respective one of the differential amplifiers.
