Latest Patents

One of Yu-chi Lee's latest patents is a low KVCO phase-locked loop with large frequency drift handling capability. This innovative phase-locked loop supports a large frequency drift capability while maintaining a low Kvco. It is designed to avoid introducing noise or discontinuities in the frequency of the generated output signal. The technology includes a voltage-controlled oscillator (VCO) with an LC tank circuit, where the capacitance can be adjusted in incremental units. By gradually adjusting a control signal applied to the VCO's LC tank circuit frequency adjustment control line, the frequency range supported by the VCO can be shifted to accommodate environmentally induced frequency drift without compromising signal integrity.
