Abstract
Backgate biases of MOS transistors for generating a bias voltage in a bias voltage generation circuit generating the bias voltages are set shallow and backgate biases of MOS transistors of delay circuits of a ring oscillator constituting a clock generation circuit are set shallow. Thereby, a voltage range and a frequency range of a voltage controlled generation circuit to implement a phase synchronizing loop are both extended.
