Abstract
An analog storage cell circuit includes a switch that minimizes subthreshold conduction and diode leakage, as well as an accumulation-mode coupling mechanism to minimize overall switch leakage to minimize accumulation-mode leakage. In one embodiment, an analog storage circuit includes a sample and hold circuit including an amplifier having first and second inputs and a switch coupled to the first input of the amplifier. The switch includes a first switching device forming a core of the switch, a second switching device coupled to the first switching device to disconnect the first switching device from a first terminal during the hold phase, and a third switching device coupled to the first switching device to connect the first switching device to a second terminal during the hold phase to minimize accumulation mode conduction in the first switching device.
