Abstract
An electrical circuit includes an amplifier. The amplifier includes an input circuit in communication with an input of the amplifier. A start-up circuit is in communication with the input circuit. The start-up circuit is configured to generate a start-up signal to enable subsequent operation of the amplifier. The start-up circuit turns off when an output of the amplifier reaches a threshold voltage. An output circuit is in communication with each of the outputs of the amplifier, the input circuit, and the start-up circuit.
