Latest Patents

One of his latest patents is titled "Phase-locked loop with a charge pump current limiting device." This invention relates to a phase-locked loop that includes a comparator and a charge pump. The comparator compares the phases of an input pulse signal and a reference pulse signal, generating charge and discharge control signals. The charge pump is capable of charging or discharging the capacitive filter based on these control signals. The filter is charged or discharged when the signals are in a first state and insulated from the charge pump when they are in a second state. Additionally, the loop features a device for limiting the charge and discharge current of the capacitive filter, which includes windowing circuits to restrict the time during which the control signals are in the first state.

Another significant patent is "Synchronization circuit and methods for screens with scanning circuits." This invention is applicable in the field of monitors, particularly in television receivers. The disclosed circuit comprises components that analyze and correct horizontal and vertical synchronization signals, neutralizing the effect of signaling present in the horizontal synchronization signal on the operation of a phase-locked loop.
