Title: Michael Kevin O’Neal and Thermal Droop Compensation in Power Amplifiers.

Introduction

Michael Kevin O’Neal is an inventor associated with Qorvo US, Inc. and based in Saratoga, California. His patent work addresses a challenge in power amplifiers: temperature-related signal droop during rapid pulsing.

Latest Patents

O’Neal is named on 1 patent, titled “Thermal Droop Compensation in Power Amplifiers.” The patent describes adding a droop compensation circuit to a temperature-sensitive active bias circuit in a power amplifier chain. Using current mirroring, the circuit draws a trigger current that a correction circuit can use to generate an additional bias signal. This signal offsets temperature-induced droop. The disclosed approaches allow variation in where the bias signal is injected and in the correction circuit design, including use of an attenuator or variable gain amplifier. The aim is to support rapid pulsing signals through an effectively linear power amplifier chain while reducing droop effects.

Career Highlights

O’Neal’s documented patent contribution focuses on improving power amplifier performance under changing thermal conditions. The patent identifies circuit techniques intended to compensate for heat-related droop during rapid signal transmission.
