Latest Patents
Feng Shen holds a patent for a "Circuit and method for reducing delay line length in delay-locked loops." This digital delay lock loop (DLL) circuit is designed for clock signals with a reduced delay line length. The invention includes a first phase difference detector for detecting a first phase difference and a second phase difference detector for detecting a second phase difference. Additionally, the circuit features an inverter for inverting an input clock signal and a switch controlled by the second phase difference detector. This switch allows for the selection between the input clock signal and the inverted input clock signal based on the second phase difference, ultimately providing a clock signal to the first phase difference detector. The method aspect of the patent involves determining a phase difference between an input clock signal and a feedback clock signal, maintaining this phase difference within approximately 180 degrees, and reducing the number of delay cells utilized by approximately one-half.
