摘要:
A variable delay circuit comprising a first delay element configured to delay an input signal, a second delay element coupled to the first delay element in parallel and also configured to delay the input signal, a control current supply section configured to supply control currents for adjusting a delay amount of the first delay element and a delay amount of the second delay element, and an output signal selecting section configured to select any one of an output signal from the first delay element and an output signal from the second delay element according to a selecting signal for selecting delay time of the input signal.
