Abstract: PURPOSE:To variably change a time constant of delay circuit parts in accordance with a frequency of an input signal by removing a pulse, having duration less than a predetermined time constant, from the input signal, and giving a current signal of value in accordance with the frequency of the input signal current mirror circuits as an output control current. CONSTITUTION:In delay circuit parts 101 to 105, follow-up of a pulse front edge part of an output signal relating to a pulse front edge part of an input signal is refused by a time constant based on flow path resistance of an output current in current mirror circuits 104, 105 and capacitance of a capacitor 111 connected in parallel to a flow path of an output current in these current mirror circuits 104, 105, so that a pulse, having duration less than the time constant, is removed from the input signal. This input signal is converted into a current signal of value in accordance with a frequency of this input signal by control current supply circuits 112, 113, and this current signal is given to the current mirror circuits 104, 105 as an output control current. In this way, the time constant of the delay circuit parts 101 to 105 can be changed in accordance with the frequency of the input signal.
