Claim 9:
10. The method of claim 9, further comprising:
providing a first flip-flop, the first flip-flop being coupled to an output of a last flip-flop of the plurality of flip-flops, having a clock input coupled to the clock signal generated by the oscillator circuit, having a reset input coupled to the reset signal, and having an output for generating a first guard signal;
providing a second flip-flop, the second flip-flop being coupled to an output of the first flip-flop, having a clock input coupled to the clock signal generated by the oscillator circuit, having a reset input coupled to the reset signal, and having an output for generating a second guard signal;
comparing the reset signal with the first guard signal to generate a first decision signal;
comparing the reset signal with the second guard signal to generate a second decision signal; and
generating the control signal to control the delay generated by the delay unit of the oscillator circuit according to the first decision signal and the second decision signal.
