Abstract
An operational amplifier includes a first stage, a second stage, and a switching unit. The first stage receives an analog input signal. The second stage has an output node coupled to an output switch. The switching unit is coupled between the first stage and the second stage. The switching unit includes a capacitive component and a first switch coupled to the capacitive component in series. The first switch is turned off when the output switch is turned on. The first switch is turned off while the analog input signal is in transition, and is turned on while the analog input signal is steady. The first switch is turned on when the output switch is turned off.
