Abstract
An electronic circuit is described including an oscillator generating an oscillating signal having a cycle responsive to an input signal, a voltage detector producing a detection signal responsive to a power supply voltage, a frequency divider generating a frequency-divided signal obtained by dividing a frequency of the oscillating signal by a frequency-division ratio responsive to the detection signal, and an adder obtaining a sum of a first signal and a second signal and to supply a signal responsive to the sum to the oscillator as the input signal. The first signal is responsive to a difference in phase between the frequency-divided signal and a reference signal, and the second signal is responsive to the detection signal. A related method is also described.
