Title: Innovations of John Joseph Hug
Introduction
John Joseph Hug is a notable inventor based in Nijmegen, Netherlands. He has made significant contributions to the field of electrical engineering, particularly in the design of circuits for power amplifiers. With a total of 5 patents to his name, Hug's work has had a considerable impact on the industry.
Latest Patents
One of Hug's latest patents is a current limiting circuit for RF power amplifiers. This innovative circuit is designed to sense the bias current fed to the final stage of the power amplifier. It compares this sensed representation of the bias current to a predetermined reference current. When the sensed representation exceeds the reference current, a signal is fed back to the power control loop to limit the output current of the amplifier. This design ensures that the current drawn by the power amplifier remains stable, even under varying supply voltage and temperature conditions. Additionally, a second circuit can be integrated to further limit the current drawn by the amplifier, enhancing its reliability under antenna mismatch conditions.
Another significant patent by Hug is an output power detection circuit. This circuit detects the output power of a power amplifier using a first current mirror transistor connected to a power transistor. The RF detection means monitors the RF current flowing through the current mirror transistor. The circuit also includes a biasing mechanism to ensure accurate detection of the output power, contributing to the overall efficiency of the power amplifier.
