ABSTRACT:
An integrating circuit is formed in the present invention, of which the active element is a pair of bipolar transistors (T5/T6) or a CMOS transistor (T8) which with the aid of switches (s81 to s88) controls the storing of a sample charge from the signal voltage (Us) in a sampling capacitor (Ci) and the discharging of the sample into an integrating capacitor (Co). The circuit only consumes current while charges are being transferred.
