摘要: An operational amplifier gain stage incorporating switched capacitor resistor equivalent circuits uses a delayed clock reference signal (φ D , φ ) to eliminate the effects of spurious error voltages (E s generated when utilizing metal oxide silicon field effect transistors as switches (12, 15, 21, 23, 25). The single remaining MOSFET switch (21) which will contribute voltage component output is designed in such manner minimize during operation switch. A dummy (31) utilized further minimise by this
