Introduction

Ovidiu Carnu is a prominent inventor based in San Francisco, CA, known for his significant contributions to power amplification technology. With a total of 9 patents to his name, Carnu has made strides in enhancing the efficiency and performance of radio-frequency systems.

Latest Patents

One of his latest innovations is the "Open-loop adaptive bias power amplifier." This power amplification system features a Power Amplifier (PA) designed to amplify an input RF signal. The adaptive bias circuit within the system is configured to set the PA's bias adaptively. It includes a gain expansion circuit, a gain compression circuit, and a biasing circuit. The gain expansion circuit derives a control signal from the input RF signal, allowing for a larger dynamic range in specific sub-ranges. Conversely, the gain compression circuit manages the dynamic range for higher power levels. The biasing circuit responsively adjusts the PA's bias based on these control signals.

Another notable patent is the "Radio-frequency front end with power amplifier detuning to reduce output degradation." This invention encompasses radio-frequency front-end circuitry that includes an output terminal and a receive amplifier. The design features transmit amplifiers that are inductively coupled to the output terminal, along with impedance elements that help reduce output degradation when the transmit amplifiers are inactive. This innovation is particularly beneficial in differential signaling applications.
