Latest Patents

One of his latest patents is a Delay Locked Loop, which includes a delay line, a phase detector, a controller, an output clock generator, and a feedback circuit. The delay line receives an input clock signal and a control code, generating a delayed clock signal by delaying the input clock signal according to the control code. The phase detector receives a reference clock signal and a feedback clock signal, detecting a phase difference between the two to generate phase comparison information. The controller generates the control code and a switching signal based on this information. The output clock generator selects either the delayed clock signal or its inverted signal according to the switching signal to produce an output clock signal. The feedback circuit then generates the feedback clock signal based on the output clock signal.

Another significant patent is the Control Circuit of Delay Lock Loop and Control Method Thereof. This control circuit includes a power status detector, a voltage comparator, an enable signal generator, and a control signal generator. The power status detector detects a transition edge of a clock enable signal to generate a trigger signal corresponding to a variation in operation power. The voltage comparator compares the operation power with a reference voltage to produce a comparison result. The enable signal generator sets an enable signal to an active state based on the trigger signal and to a non-active state according to the comparison result. The control signal generator outputs a control clock to generate a control signal when the enable signal is active.
