Latest Patents

One of her latest patents is titled "Multiplying Delay Locked Loops with Compensation for Realignment Error." This invention provides a method for improving the functionality of multiplying delay locked loops (MDLLs). The MDLL includes a control circuit, a multiplexed oscillator, and an integrate and subtract circuit. The control circuit selectively injects a reference clock signal into the multiplexed oscillator, which operates with an injected period when the reference clock signal is present and with a natural period when it is not. The integrate and subtract circuit tunes the oscillation frequency of the multiplexed oscillator based on the difference between the integration of the oscillator signal over both periods.

Another notable patent is related to "Methods for Controlling Frequency Synthesizers." This invention discloses systems and methods for controlling frequency synthesizers to reduce or eliminate reference spurs. The control system can be implemented in a phase-locked loop (PLL) of a frequency synthesizer. It includes a phase detector that generates a signal representative of the phase difference between a reference signal and a feedback signal. The control system also features a charge pump that generates a compensation signal to enhance the output signal of the oscillator, effectively reducing reference spurs.
