A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal.
Supply voltage tolerant phase-locked loop circuit
A phase-locked loop design is provide that can operate at a plurality of dissimilar supply voltages. By adjusting the frequency range of a PLL based on the power supply voltage, the same PLL design can operate at different supply voltages.
