Latest Patents

Chih-Chiang Liu holds a patent for a "Clock de-skewing delay locked loop circuit." This invention reveals a sophisticated design where a timing control circuit generates both a first and a second clock signal based on external and internal clock signals. The circuit includes a clock delay line that delays the first clock signal or the external clock signal to produce delay signals. A delay mirror circuit is employed to synchronize the internal clock signal with the external clock signal. Additionally, a phase adjustment circuit inverts the internal clock signal according to the phase difference, while an inverting buffer circuit buffers the external clock signal or the first clock signal to add an initial delay time. This design ensures that the duty cycle of the internal clock signal and the external clock signal complement each other, allowing the external clock signal's duty cycle to deviate from the conventional 50%.
