Abstract
1392376 Electric analogue calculating LICENTIA PATENT-VERWALTUNGS-GmbH 4 Aug 1972 [11 Aug 1971] 36478/72 Heading G4G A sample-and-hold circuit in which a voltage representative of an input signal U1 has to be stored in a capacitor C for a period of time comprises a comparator K which receives as inputs the input signal U1 and (via buffer amplifier V) the voltage stored on capacitor C, the comparator controlling through logic circuit L two current sources I 2 , I 3 which charge capacitor C in such a way as to make the inputs to comparator K equal. The sample-and-hold sequence is determined by gating signals t ab and t H . The output signal U3 is taken from terminals T1, T2.
