Title: Vincent C. Barnes: Innovator in Digital Predistortion Technologies

Introduction

Vincent C. Barnes is a prominent inventor based in El Paso, TX (US), known for his significant contributions to digital predistortion technologies. With a total of 8 patents to his name, he has made remarkable advancements in the field of communication systems.

Latest Patents

One of his latest patents is titled "Systems and methods for digital predistortion to mitigate power amplifier bias circuit effects." This patent describes a digital predistortion (DPD) system that includes an input configured to receive an input signal. The system features a first signal path that generates a first signal based on the input signal. Additionally, it includes an error model provider that generates an error model signal modeled after a gate bias error voltage associated with the DPD system. A first combiner is also part of the system, which combines the first signal and the error model signal to generate a first intermediate signal, allowing the DPD system to produce an output signal based on this intermediate signal.

Another notable patent is "Time constant tracking for digital pre-distortion." This invention involves a transmitter for a communication system that comprises a digital pre-distortion (DPD) circuit and adaptation circuitry. The DPD circuit generates a digital intermediate signal by compensating an input signal for distortions resulting from an amplifier. The amplifier outputs an output signal based on the digital intermediate signal. The DPD circuit includes one or more infinite impulse response (IIR) filters that implement a first transfer function based on a first parameter, and a second transfer function based on the first parameter and a time constant. The adaptation circuitry updates the first parameter based on the adjustment signal, the input signal, and the output signal.
