Abstract
A substrate bias circuit and method for biasing a substrate are provided. A substrate bias circuit includes a first voltage source, a second voltage source, a diode coupled between the first voltage source and the second voltage source, and a plurality of transistors, each transistor in the plurality of transistors having a substrate terminal. In one example, the first voltage source supplies, via the diode, the substrate terminal of a first transistor of the plurality of transistors during a power-up, and the second voltage source supplies the substrate terminal of the first transistor after the power-up.
