Abstract
An electronic circuit, includes: a first oscillator configured to generate a reference signal; a plurality of phase synchronization circuits, each including a second oscillator configured to generate an output signal having a frequency corresponding to an input, and a phase comparator configured to input, to the second oscillator, a signal corresponding to a phase difference between the output signal generated by the second oscillator and the reference signal generated by the first oscillator; and a controller configured to control relative phases of the reference signals input to the phase synchronization circuits from the first oscillator, based on the signals input to the corresponding second oscillators from the phase comparators in the phase synchronization circuits.
