Title: John Bellantoni and Thermal Droop Compensation in Power Amplifiers.

Introduction

John Bellantoni is an inventor associated with Qorvo US, Inc. and based in San Jose, California. His patent work addresses a challenge in power amplifiers: temperature-induced signal droop during rapid pulsing.

Latest Patents

Bellantoni is named on 1 patent, titled “Thermal Droop Compensation in Power Amplifiers.” The invention 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, helping the amplifier transmit rapid pulses while maintaining effective linearity. The patent also describes variations in where the bias signal is introduced and in the correction circuit’s design, including an attenuator or variable gain amplifier.
