Title: Eric Souchard and His Frequency Synthesizer Invention.

Introduction

Eric Souchard is an inventor associated with Châtillon, France. His recorded patent describes a frequency synthesizer designed to achieve very short acquisition times. The available information lists 1 patent for him.

Latest Patents

Souchard’s patent, “Single Loop Frequency Synthesizer with Direct Digital Synthesis,” combines a single-loop synthesizer with a direct digital synthesizer. The digital synthesizer’s signal is injected into the loop through a mixer. The design adjusts the loop at Np·Fr and the digital synthesis at (Ns + K/M)·Fr, where Np, Ns, K, and M are integers, Np is greater than Ns, 0 ≤ K < M, M is fixed, and Fr is the reference frequency. Mixing the signals produces a synthesis frequency of (Ns + Np + K/M)·Fr. The digital synthesis has negligible acquisition time, while the loop’s acquisition time is reduced because it synthesizes steps that are multiples of Fr rather than the finer steps used in a standard single-loop design.

Career Highlights
