This is a circuit of low drift sample and hold. This circuit uses two JFET, Q1 and Q2 that provides the sample and hold capacitor, C1. Q1 provides a path, Rds(on), for C1 and turned on during sample. Q2 IGSS (<100 pA) and Q1 ID(OFF) (<50 pA) as the only discharge paths because Q1 is …

This is a simple sample and hold with offset adjustment circuit. Sample and hold circuit is used to operate on analog information in a time frame which is expedient. This circuit works by sampling a segment of the information and holding it. And then convert it into some readout or form of control signal. Here …
