ABSTRACT:
A digital voltage level measuring device includes an amplifier having a capacitive feedback the output voltage of which is brought to a value dependent upon the integration result reached within a given interval of time of a voltage to be measured. After disconnection of the voltage which is to be measured, the output voltage is fed back to the amplifier input. The interval of time from the beginning of the feedback phase until the reaching of a given voltage value by the exponentially changing output voltage is then digitally measured.
