摘要
A method uses a controlled oscillator to output an oscillation signal in accordance with a control signal. The method operates by using a first divide-by-1.5 circuit to convert the oscillation signal into a first divided-down signal, using a second divide-by-1.5 circuit to convert the first divided-down signal into a second divided-down signal, using a divide-by-2 circuit to convert the second divided-down signal into a LO (local oscillator) signal, using a modulator to modulate the LO signal into a RF (radio frequency) signal in accordance with a baseband signal, and using a controller to establish the control signal in accordance with a relative timing between a reference signal and the oscillation signal.
