Abstract
A sample-and-hold circuit comprises a sampling capacitor; an amplifier transistor; and a noise reduction circuit including an integration capacitor and a feedback capacitor, the noise reduction circuit being configured to reduce noise via a four-phase operation including: an auto-zero phase in which the feedback capacitor is discharged, a feedback phase in which a gate voltage of the amplifier transistor is partially compensated through the feedback capacitor, an integration phase in which the integration capacitor is charged, and a feedforward phase in which the gate voltage of the amplifier transistor is fully compensated by a voltage on the integration capacitor through the feedback capacitor.
