Abstract:
A signal generation device is provided to generate an output signal with constant frequency. The signal generation device includes a frequency-control circuit and a voltage-controlled delay line. The frequency-control circuit includes a pulse generator, generating a reference pulse signal according to a transition of the reference signal and a comparison pulse signal according to a transition of the comparison result signal, to re-shape the reference signal and the comparison result signal into narrow pulses suitable for clocking and resetting flip-flops.
