PHASE-LOCKED LOOP DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240120927 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, a divider, a sampling phase frequency detector, a transconductance circuit, and a loop filter.
- The voltage controlled oscillator generates an output clock signal.
- The divider divides the output clock signal into first and second phase division signals with a constant phase difference.
- The sampling phase frequency detector samples a sampling voltage based on the first phase division signal and outputs a voltage control signal based on the conversion current.
- The 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 outputs it to the voltage controlled oscillator.
