ANALOG INTEGRATOR Russian patent published in 2015 - IPC G06G7/18 

FIELD: measurement equipment.

SUBSTANCE: analogue integrator comprises sources of input and reference voltages, a switch, the main integrating amplifier, an additional integrating amplifier, the main comparator, a summing chronometer and a control unit, an additional comparator and a capacitor, at the same time the first and second inputs of the additional comparator are connected accordingly to the output of the main integrating amplifier and to the source of the input voltage, the first input of the main comparator is connected to the point with zero potential, outputs of the main and additional comparators are connected to inlets of the control unit, the outlets of the latter are connected to the switch and the summing chronometer, and the capacitor is connected between the second output terminal of the reference voltage source and the input of the main integrating amplifier.

EFFECT: reduced non-linearity and increased accuracy during integration of values of input signals in a wide range.
