Title: Vahid M Naraghi: Innovator in Time Synchronization Technologies

Introduction

Vahid M Naraghi is a notable inventor based in San Jose, CA. He has made significant contributions to the field of time synchronization technologies, holding 2 patents that showcase his innovative approach to solving complex problems in electronic systems.

Latest Patents

One of his latest patents focuses on detecting time delay between circuits to achieve time synchronization. This patent outlines systems, circuits, and methods for synchronizing devices in the time-domain. The method includes determining a round-trip number based on the width of one cycle of a timestamping clock signal. This round-trip number represents the number of times a clock signal is transmitted in a loop from a timing-leader component to a timing-follower component and back. The method also utilizes the timestamping clock signal to detect a cumulative time delay, enabling synchronization of the timing-follower component with the timing-leader component.

Another significant patent by Naraghi involves carrying a timestamp in Radio over Ethernet (RoE). This innovation includes a node with a clock and mapper circuitry that determines a timestamp from the clock. The timestamp is then transmitted to a second node in a RoE frame, allowing for effective synchronization between nodes. The demapper circuit at the second node receives a second timestamp, which is used for adjusting the clock to ensure accurate timing.
