Abstract: A multiplexer comprises: a first switch; a second switch; a dummy component coupled to the first switch and the second switch and configured to: reduce a first charge injection of the first switch, and reduce a second charge injection of the second switch; and an output coupled to the first switch, the second switch, and the dummy component. A method comprises: providing an output from either a first switch or a second switch; coupling, by a dummy component, to the first switch and the second switch; using a BBM action; and reducing, by the dummy component, a first charge injection of the first switch or a second charge injection of the second switch.

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.
