    摘要: The provided delay lock loop delaying an input signal includes a quadrature generator, a voltage controller and a delay cell. The input signal is inputted into the quadrature generator and the delay cell. A phase-changing signal from the quadrature generator and a delay signal respectively from the delay cell are inputted into the voltage controller at the same time so that a control voltage inputted into the delay cell to control a delay time of the delay signal is generated. Also, the provided phase angle generator generates an output signal in an arbitrary phase.
