Latest Patents
Fang Shen's latest patents include a "Delay lock loop circuit, system and method for synchronizing a reference signal with an output signal." This invention discloses a method and system for synchronizing a reference signal and an output signal produced by an electrical circuit, which comprises both an analog and a digital portion. The method involves utilizing the digital portion to produce a phase-adjusted signal while the analog portion generates an output signal that is in substantial phase alignment with the phase-adjusted signal. This innovation eliminates the need for a large bi-direction shift register found in conventional hybrid DLLs, enabling high-speed DLLs to provide high-resolution deskewed clocks more efficiently. Additionally, it allows for a broader range of clock frequencies.
Another notable patent is the "Circuit and method for reducing lock-in time in phase-locked loops." This invention provides methods and circuit aspects aimed at improving lock-in time following power-up in a phase-locked loop. The circuit includes a low pass filter and a pulse generation circuit that is coupled to the low pass filter. The pulse generation circuit generates a control pulse of predetermined duration to enhance the voltage across the low pass filter, thereby reducing lock-in time in the phase-locked loop after power-up.
