Introduction

Eric Cirot is a notable inventor based in Fontaine, France. He has made significant contributions to the field of signal processing, holding a total of 4 patents. His work primarily focuses on phase-locked loops and synchronization signal treatment circuits, which are essential in various electronic applications.

Latest Patents

One of Eric's latest patents is a "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 a 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 in a second state. Additionally, the loop features a device that limits the charge and discharge current of the capacitive filter, utilizing windowing circuits to restrict the time during which the control signals are active.

Another significant patent is for a "Circuit for the treatment of synchronization signals." This circuit processes an input signal containing line sync pulses used for displaying data on a screen. It incorporates a phase-locked loop to control horizontal sweeping according to the active edges of line sync pulses. Furthermore, it includes a filter circuit that filters equalizing signals from the input signals, providing a filtered input signal to the phase-locked loop.
