ABSTRACT:
For the purpose of detection of a zero-cross point of an input signal, the input is applied to one of two input terminals of a comparator which has an inverted input terminal and a non-inverted input terminal, the same bias voltage is applied to each of two input terminals of the comparator from a bias voltage supplying circuit, the value of the bias voltage applied to either the inverted input terminal or the non-inverted input terminal of the comparator is changed by a bias voltage changing circuit from that determined by the bias voltage supplying circuit depending on whether the output of the comparator is in its high or low level, the output of the comparator is a detection signal of the zero-cross point of the input signal.
