一種資料時脈回復電路，用以接收資料信號且產生一時脈信號。此資料時脈回復電路包括震盪器、相位偵測器、以及第一電壓-電流轉換器。震盪器根據震盪電壓來產生時脈信號。相位偵測器接收資料信號。此相位偵測器包括混波器，用以偵測資料信號與時脈信號間之相位差，並產生表示相位差之相位偵測信號。第一電壓-電流轉換器接收相位偵測信號，並根據相位偵測信號之電壓來產生第一電流信號來改變震盪電壓。
A clock and data recovery (CDR) circuit is provided. The CDR circuit receives a data signal and generates a clock signal. The CDR circuit comprises an oscillator, a phase detector, and a first voltage-to-current (V-to-I) converter. The oscillator generates the clock signal according to an oscillation voltage. The phase detector receives the data signal. The phase detector comprises a mixer for detecting a phase difference between the data clock and the clock signal and generating a phase detection signal which represents the phase difference. The first V-to-I converter receives the phase detection signal and generates a first current signal according to a voltage level of the phase detection signal to vary the oscillation voltage.
