Latest Patents

One of his latest patents is titled "Non-linear charge pump for phased lock loops." This invention features a non-linear charge pump designed to enhance the performance of phase-locked loops. The apparatus includes a positive switch connected to a current source, which supplements power to the charge pump, and a negative switch connected to a current sink, which discharges power from the charge pump. Additionally, it incorporates a windowing comparator that receives an input signal from a phase-locked loop, along with two comparators that assess the input signal against high and low voltage thresholds. An AND logic gate provides a window signal, and an activation circuit connects to both switches. Another significant patent is the "Analog lock detector for a phase lock loop." This invention includes a detector that outputs signals related to synthesized and reference frequencies, a logic gate that combines these signals into an initial lock signal, and a delay circuit that produces a delayed lock signal. The final lock signal indicates when the synthesized frequency is locked to the reference frequency.
