Systems and Methods for Phase Locked Loop Realignment With Skew Cancellation - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446881 titled 'Systems and Methods for Phase Locked Loop Realignment With Skew Cancellation

Simplified Explanation

The patent application describes a phase locked loop system and method.

• The system includes a phase/frequency detector that receives a reference signal and a feedback signal.
• A charge pump is connected to the phase/frequency detector and generates pulses based on its outputs.
• An oscillator generates an output waveform using the pulses from the charge pump.
• A realignment path generates a clock realignment signal for the oscillator based on the outputs from the phase/frequency detector.

Original Abstract Submitted

Systems and methods are provided for a phase locked loop. A phase/frequency detector is configured to receive a reference signal and a feedback signal. A charge pump is configured to receive outputs from the phase/frequency detector and to generate pulses. An oscillator is configured to generate an output waveform based on the charge pump pulses. A realignment path is configured to generate a clock realignment signal that is provided to the oscillator based on the outputs from the phase/frequency detector.
