Split Bias with Single Control Current Source for Radio Frequency Power Amplifier - A simplified explanation of the abstract

This abstract first appeared for US patent application 18463569 titled 'Split Bias with Single Control Current Source for Radio Frequency Power Amplifier

Simplified Explanation

The abstract describes a power amplifier that consists of two driver stages and a biasing component. The biasing component includes two emitter follower circuits and is designed to receive a source current from a current source. It provides a bias voltage to each driver stage based on the current source.

  • The power amplifier includes a first and second driver stage.
  • It also includes a biasing component with two emitter follower circuits.
  • The biasing component receives a source current from a current source.
  • It provides a bias voltage to each driver stage using the emitter follower circuits.
  • The bias voltages are determined by the current source.

Potential applications of this technology:

  • Power amplifiers are commonly used in audio systems, telecommunications, and wireless communication devices.
  • This technology can be applied in any device that requires amplification of electrical signals.

Problems solved by this technology:

  • Power amplifiers often require precise biasing to ensure optimal performance.
  • This technology solves the problem of providing accurate bias voltages to the driver stages.

Benefits of this technology:

  • The use of two driver stages allows for increased power output and improved signal quality.
  • The biasing component ensures stable and accurate bias voltages, resulting in better overall performance of the power amplifier.


Original Abstract Submitted

A power amplifier includes a first driver stage, a second driver stage, and a biasing component including a first emitter follower circuit and a second emitter follower circuit. The biasing component is configured to receive a first source current from a first current source, and provide a first bias voltage to the first driver stage using the first emitter follower circuit and a second bias voltage to the second driver stage using the second emitter follower circuit. The first bias voltage and the second bias voltage are based upon the first current source.
