PHASE-LOCKED LOOP DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18142939 titled 'PHASE-LOCKED LOOP DEVICE AND OPERATION METHOD THEREOF
Simplified Explanation
The abstract describes a phase-locked loop device that includes a voltage controlled oscillator, divider, sampling phase frequency detector, transconductance circuit, and loop filter.
- The device generates an output clock signal using a voltage controlled oscillator.
- The output clock signal is divided into first and second phase division signals with a constant phase difference.
- A sampling phase frequency detector samples a voltage based on the first phase division signal and outputs a voltage control signal based on the second phase division signal.
- A transconductance circuit outputs a conversion current based on a hold voltage.
- The loop filter generates a voltage control signal based on the conversion current and sends it to the voltage controlled oscillator.
