Abstract:
An oscillating signal generator includes: a controllable oscillator arranged to output an oscillating signal according to a control signal and a band adjusting signal; a control circuit arranged to generate a continuous signal having a specific slew-rate when the control signal reaches a boundary of a control signal interval; and a current mirror arranged to generate the band adjusting signal according to at least the continuous signal.
