Abstract: 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.
