Abstract
A voltage comparator circuit that is useful in A/D converters and D/A converters. The circuit comprises a comparison capacitor, a holding capacitor and input switching transistors. The holding capacitor holds the comparison voltage applied to it from the input switching transistors through the comparison capacitor. Therefore, the circuit can perform accurate voltage comparison even if the input voltages are sampled at a high sampling frequency.
