Latest Patents

One of Jianyun Hu's latest patents is titled "PLL post divider phase continuity." This invention provides a phase continuity architecture that maintains the phase continuity for a post divider output signal from a phase-locked loop (PLL) output signal. The design includes a pulse swallower that removes a pulse from the PLL output signal in response to an edge of a divided feedback clock signal. Additionally, a sampler samples the post divider output signal to determine the phase relationship between the post divider output signal and the divided feedback clock signal.

Another significant patent is for an "Apparatus and method for generating an oscillating output signal." This apparatus includes an inductive-capacitive (LC) circuit and a current tuning circuit. The LC circuit features a primary inductor and a varactor, with the capacitance of the varactor being responsive to a control voltage. The current tuning circuit comprises a secondary inductor and a current driving circuit, which adjusts the effective inductance of the primary inductor through magnetic coupling. The frequency of the oscillating output signal is influenced by both the effective inductance and the capacitance of the varactor.
