Abstract
The delay circuit of the present invention has a CR integrator including a variable capacitance diode. This CR integrator is arranged between the first and second comparators. By applying a constant DC comparison voltage to the other input terminal of the second comparator, delay amounts can be selectively changed for the leading and trailing edges of the pulse waveform.
