ABSTRACT:
A voltage comparator includes a coupling capacitor which receives at one terminal thereof two signals applied in a complementary fashion, an inverting amplifier having an input coupled to the other terminal of the coupling capacitor and having an output, and switch means coupled between the input and output of the inverting amplifier so as to be in parallel with the inverting amplifier. The duration of an auto-zeroing interval during which the switch means is conductive is maintained constant regardless of the period of the ON-OFF operation of the switch means.
