Document Type and Number:
WIPO Patent Application WO/2023/184575
Kind Code:
A1
Abstract:
A loop filter (300) for a phase-locked loop and a phase-locked loop. The loop filter (300) comprises a first resistor (310), a first capacitor (320), and a second capacitor (330). The first resistor (310) and the first capacitor (320) are connected between an input end and a grounding end of the loop filter (300), and the second capacitor (330) is connected between an output end and a grounding end of the loop filter (300). The loop filter (300) further comprises a bridging circuit, and the bridging circuit is connected between the input end and the output end of the loop filter (300) and is used for dividing the voltage of an input signal of the loop filter (300).
