PRE-BIASED DUAL CURRENT SENSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827406 titled 'PRE-BIASED DUAL CURRENT SENSING

Simplified Explanation

The patent application describes a system that includes transistors and circuitry to provide current to a load. It also includes a sense transistor to measure the current flowing through one of the transistors. An amplifier is connected to the sense transistor and has inputs and an output. Pre-bias circuitry is included to provide a voltage to the amplifier when the first transistor is off, which helps to bias the amplifier.

  • The system includes transistors and circuitry to provide current to a load.
  • A sense transistor is used to measure the current flowing through one of the transistors.
  • An amplifier is connected to the sense transistor and has inputs and an output.
  • Pre-bias circuitry is included to provide a voltage to the amplifier when the first transistor is off.
  • The voltage from the pre-bias circuitry helps to bias the amplifier.


Original Abstract Submitted

In an example, a system includes a first transistor and a second transistor, the first transistor and the second transistor configured to provide current to a load. The system also includes a sense transistor coupled to the first transistor, the sense transistor configured to sense a current flowing through the first transistor. The system includes an amplifier coupled to the sense transistor, where the amplifier includes a first input, a second input, and an output. The system also includes pre-bias circuitry coupled to the amplifier, where the pre-bias circuitry is configured to provide a voltage to the first input of the amplifier responsive to the first transistor being off, where the voltage biases the amplifier.
