Abstract
A frequency generating circuit includes: a delay circuit, arranged to operably delay an output frequency signal to generate a delayed signal; a quartz crystal resonator, coupled with the delay circuit, arranged to operably conduct a band-pass filtering operation on the delayed signal to generate the output frequency signal; and a delay control circuit, coupled with the delay circuit, arranged to operably control a phase delay amount of the delay circuit to thereby control the phase of the delayed signal.
