摘要: The invention provides a hybrid phase-locked loop (PLL) containing digital and analog portions for adjustments, respectively, of an output signal. PLL is simple in design. Off-the-shelf controlled oscillators, such as current oscillator (CCO) can be used with this PLL. the are separate from oscillator. portion first adjustment frequency signal, during calibration. fine phase
