Abstract
A circuit includes a first passive device between supply and bias nodes, a first switching device and a second passive device between the bias and a reference node, a transistor between the supply and an output node, a third passive device and a second switching device between the output and a feedback node, a fourth passive device between the feedback and reference nodes, a third switching device between the supply and output nodes, and an amplifier controlling the transistor based on bias node and feedback node voltages. In a first mode, the first and second switching devices are off, the third switching device is on, and the supply node receives a first voltage level. In a second mode, the first and second switching devices are on, the third switching device is off, and a second voltage level greater than the first voltage level is received on the supply node.
