Title: Abolfazl Khosrowbeygi: Innovator in Signal Measurement Technology

Introduction

Abolfazl Khosrowbeygi is a notable inventor based in Cupertino, CA, who has made significant contributions to the field of signal measurement technology. He is recognized for his innovative approach to developing systems and methods for measuring signal power, particularly in scenarios where the signal is substantially variable or time-varying.

Latest Patents

Khosrowbeygi holds a patent for a "Logarithmic RMS-detector with servo loop." This invention focuses on systems and methods for measuring signal power when the signal is subject to variability. The patent describes a log-linear variable gain amplifier (VGA) that is coupled in a feedback configuration to a difference-of-squares detector and an integrator. The log-linear VGA features a set of selectable amplifier cells, allowing for enhanced signal processing. A sliding current generator selects one or more amplifier cells, producing a sum of outputs. Some amplifier cells provide differential amplification, while others offer similar amplification with differential attenuation. The design includes switches that isolate unselected amplifier cells, and canceling circuits that produce an output opposite to those cells, ensuring a sum near zero. Additionally, the invention incorporates temperature compensation and adjustment capabilities, allowing the log-linear VGA to modify either the offset or slope based on the relationship between the output and input.
