Dynamic Bias for Doherty PA - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18344463 Titled 'Dynamic Bias for Doherty PA'
Simplified Explanation
The abstract describes a circuit that includes a Doherty power amplifier circuit. This circuit is designed to amplify an input signal and produce a stronger version of that signal. The Doherty power amplifier circuit consists of a first power amplifier circuit that operates in class C. Additionally, the circuit includes a bias circuit that is connected to the first power amplifier circuit. The purpose of the bias circuit is to generate a bias, which is a specific voltage or current level, based on the input signal. This bias is then used to properly operate and control the first power amplifier circuit.
Original Abstract Submitted
A circuit includes a Doherty power amplifier circuit configured to amplify an input signal and generate an amplified signal of the input signal. The Doherty power amplifier circuit includes a first power amplifier circuit configured to operate in class C. The circuit further includes a bias circuit electrically coupled to the first power amplifier circuit. The bias circuit is configured to generate a bias based on the input signal, and to bias the first power amplifier circuit using the generated bias.
