Resistive Switching Sample and Hold

摘要

A nonvolatile sample and hold circuit can include a resistive switching circuit, a sample circuit, a reset circuit, and a converter circuit. The resistive switching circuit can be operable to accept an input voltage Vg, and provide a resistance response Rrs that corresponds to the input signal Vg. The sampling circuit can be operable to sample an input signal such as an input voltage Vin, to provide a sampled voltage Vg. The reset circuit can be operable to reset the resistive switching circuit to a high resistance state. The converter circuit can be operable to convert the resistive switching circuit to an output voltage. The novel sample and hold circuit can have no issues related to charge injection, no settling time and instantaneous sampling time, together with potentially infinite hold time.
