Summary :

A Switched-Opamp is a device in SC circuits for replacing switches with Opamps which operate like a switch. This technique can be acheived in very low voltage operation. In this paper, we present a design for a Switched-Opamp that can operate at a low supply voltage during the ON-phase and can maintain a high output impedance during the OFF-phase.
