Title:
【発明の名称】位相検出器
Document Type and Number:
Japanese Patent JP2002507850
Kind Code:
A
Abstract:
There is disclosed a phase detector which triggers on both rising and falling edges of an input pulse signal. This effectively doubles the frequency of the input signal. When the phase detector is used in a phase locked loop, the doubled frequency means that a lower division ratio can be used, thereby reducing any noise contribution introduced thereby.
