Abstract

The precision integrator uses an operational amplifier acting as an integrator and an analogue summator which adds two currents (I1, I2) at the input (A) of the integrator. One of the currents (I2) is provided by discharging a capacitor (C2), which is selectively coupled across a voltage generator (GTR), the quantity of electricity supplied being dependent on the capacitance multiplied by the voltage output (Vr) of this source. The output of the analogue integrator (S) is coupled to an inverter (3) via a flip-flop (4) and is also coupled to a level detector (5) via a double rectifier (6). The level detector controls a monostable circuit (7) coupled to the switches for connecting the capacitor (C2) across the voltage generator via the inverter.
