Abstract:
In some examples, a circuit is described. The circuit may include a voltage-controlled oscillator that may be configured to generate an output signal. The circuit may also include a control signal generation unit that may be configured to generate a control signal based on the output signal. The control signal generation unit may also be configured to provide the control signal to the voltage-controlled oscillator. The voltage-controlled oscillator and the control signal generation unit may be part of a phase-locked loop (PLL) included in the circuit. The circuit may also include a feed-forward network. The feed-forward network may be configured to provide a portion of the control signal to the voltage-controlled oscillator. The voltage-controlled oscillator may generate the output signal based on the control signal from the control signal generation unit and the portion of the control signal from the feed-forward network.
