Abstract
A voltage comparator suitable for use in an analog-to-digital converter such as a successive-approximation converter, and provided with capacitively cascade-connected inverter stages to produce an output signal of a logic level 1 or 0 according to the relationship between the magnitudes of two analog input voltage signals to be compared. A first series circuit of an MOS switching transistor and resistive element is connected between the input and output of the respective inverters; a second series circuit of a MOS switching transistor and resistive element is connected between the input of each inverter and circuit ground. The MOS transistors of the first and second series circuits are simultaneously enabled or disabled by a clock pulse; and two input voltage signals to be compared are alternately applied to the first stage coupling capacitor.
