Abstract
A frequency-generating circuit includes a frequency synthesizer circuit and a controller. The frequency synthesizer circuit generates a radio-frequency clock signal according to a reference clock signal and a channel number. The controller is coupled to the frequency synthesizer circuit, generates a power-down control signal for controlling at least a portion of the frequency synthesizer circuit to power down. The frequency synthesizer circuit includes an accumulator for generating an accumulated value according to the channel number. The frequency synthesizer circuit generates the radio-frequency clock signal according to the reference clock signal and the accumulated value. The controller maintains the accumulated value of the accumulator when the portion of the frequency synthesizer circuit powers down.
