Abstract
A phase-locked loop (PLL) is disclosed. One embodiment, among others, includes a PLL that provides a control signal and a square root module configured to receive state information, the state information corresponding to tuning information, the square root module further configured to multiply the control signal by a square root of the state information to provide a tuning signal.
Claims30
A method for operating a phase-locked loop (PLL), said method comprising:
- providing a control signal;
- receiving state information, the state information corresponding to tuning information;
- multiplying the control signal by a square root of the state information to provide a tuning signal;
- and
- providing the tuning signal to a capacitor array, the capacitor array comprising a weighted variable capacitor and a weighted switched capacitor.
