Diodes bridge sample-and-hold circuit.

摘要

The device comprises an input amplifier (A1), a stage having a Schottky diode (D1-D4) bridge for sampling and analog storage, comprising a capacitor (CM), an output amplifier (A2) and a continuous-link control stage consisting of a symmetrical differential amplifier with transistors (rs (Q'1, Q'2) which are coupled-emitter configured. Application in particular to the sampling of video signals delivered by charge-transfer matrix image sensors. <IMAGE>
