发明名称 OPERATIONAL AMPLIFIER FOR DRIVING LARGE CAPACITOR
摘要 PURPOSE: An operational amplifier for driving a large capacitor is provided to reduce power consumption by adding a control circuit to drive the capacitor with charging/discharging currents. CONSTITUTION: An input amplifier(410) receives a first signal at a positive signal input terminal thereof, receives a second signal at a negative signal input terminal thereof, amplifies the difference between the first signal and the second signal, and outputs the amplified signal. An output unit(420) receives the third signal from the input amplifier(410), outputs a fifth signal having a first logic stage, receives a control signal having a second logic stage, and outputs a fourth signal. A controller(430) receives the fifth signal having the first logic stage from the output unit(420) to inverse the fifth signal and outputs the control signal having the inversed second logic stage.
