Abstract:
An apparatus is disclosed that implements a sampling phase-locked loop. In an example aspect, the apparatus includes a phase frequency detector, a relative phase signal determiner, a voltage-controlled oscillator (VCO), and a feedback path. The phase frequency detector is configured to produce a phase indication signal based on a reference signal and a feedback signal. The relative phase signal determiner is coupled to the phase frequency detector and includes a sampler. The relative phase signal determiner is configured to determine a relative phase signal based on the phase indication signal using the sampler. The VCO is coupled to the relative phase signal determiner and is configured to produce an oscillating signal based on the relative phase signal. The feedback path is disposed between the VCO and the phase frequency detector. The feedback path is configured to provide the feedback signal to the phase frequency detector using the oscillating signal.

Claim (Index 6):
An electronic device comprising:\n a phase frequency detector configured to produce a phase indication signal based on a phase difference between a reference signal and a feedback signal; current means for generating a charge signal responsive to the phase indication signal, the charge signal including a substantially constant positive current responsive to the phase indication signal representing a positive phase difference, the current means coupled to the phase frequency detector and comprising:\n generation means for generating a slope signal based on the phase indication signal, the slope signal indicative of whether the reference signal leads or lags the feedback signal; and \n sampling means for sampling the slope signal responsive to at least one clock signal using at least one switch to produce a sampled signal for the charge signal, the sampled signal representative of a present value of the slope signal, the sampling means configured to cause the sampled signal to cease representing the present value of the slope signal using the at least one switch and responsive to the at least one clock signal; \n a voltage-controlled oscillator coupled to the current means and configured to produce an oscillating signal based on the charge signal; and a feedback path disposed between the voltage-controlled oscillator and the phase frequency detector, the feedback path configured to provide the feedback signal to the phase frequency detector using the oscillating signal.
