12 ABSTRACT: Electronic analogue switching device comprises a differential operational amplifier with a feedback cir- cuit between its output and its inverting (-) input such that its (low impedance) output voltage follows the input signal voltage applied to its non-inverting (+) input. The output voltage is sampled by a first switch and the samples are passed to the device output where, for example ,they may be stored on a capacitor. The feed- back circuit has two paths, one via a feedback impedance and the other via the first and a second switch operated synchronously with the first switch by control means. The "on" impedance of the first switch is greatly reduced by including it in the feedback circuit, and the futher inclusion of the second switch and the impedance substan- tially eliminates unwanted transient voltages that would otherwise occur under some circumstances when the first switch operates. The device is particularly suitable for use in sample-and-hold circuits.
