ABSTRACT:
A highspeed voltage comparing operation by a voltage comparing circuit is realized while input sampling timing can be made constant. This voltage comparing circuit is mainly arranged by a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a sixth switch, a seventh switch, a eighth switch, a first capacitor, a second capacitor, a first inverter, a second inverter, a third capacitor, and a fourth capacitor. In this voltage comparing circuit, an input signal voltage is held in the first capacitor and also a reference voltage is held in the second capacitor in an input sampling mode. Then, electron charges stored in these capacitors are redistributed, and the difference voltage between the input voltage and the reference voltage is amplified by two sets of inverters in an amplifying mode. In a latch mode, these first and second inverters are operated as a flip-flop circuit. Consequently, in this voltage comparing circuit, the sampling timing of the input voltages can be correctly and periodically determined, so that the precision of the input signal comparing process operation can be improved.
