Process compensated phase locked loop |
摘要 |
A phase locked loop having a voltage-controlled oscillator is adjusted to compensate for process variations in the formation of the phase locked loop. In each instance of the phase locked loop, the center frequency of the voltage-controlled oscillator is adjusted using a bias signal while holding the control voltage of the voltage-controlled oscillator at zero. Then, the control voltage of the voltage-controlled oscillator is set to a different value and the gain of the voltage-controlled oscillator is adjusted.
