A novel SC (Switched-Capacitor) offset- and gain-compensated sample/hold circuit is presented. It is implemented by a new topology which reduces the effects due to the imperfections of op-amp. Simulation results indicate that the circuit achieves high accuracy without requiring high-quality components.
