Patent number: 11616502Abstract: A phase interpolator capable of preventing a glitch from being generated during a clock signal switching operation and a clock signal selector thereof are provided. The clock signal selector includes a selector and a selection signal generator. The selector receives multiple clock signals with different phases. The selector selects one of the clock signals according to a selection signal to generate a selected clock signal. The selection signal generator is coupled to the selector and generates the selection signal. When the selector switches from selecting a first clock signal to selecting a second clock signal as the selected clock signal, the selection signal generator generates a set time point according to a transition point of one of the first clock signal and the second clock signal whose phase lags behind a phase of the other, and generates the selection signal according to the set time point.Type: GrantFiled: November 30, 2021Date of Patent: March 28, 2023Assignee: ALi CorporationInventors: Yi Ting Chen, Ming-Ta Lee
