Abstract
A power management device is provided including a circuit module configured to provide a set of voltage biases for one or more target devices. The circuit module includes a set of first transistors of a first type and disposed in a doped region, a set of well ties disposed in the doped region and located a predetermined distance from the set of first transistors, a set of second transistors of a second type and disposed outside the doped region, and a set of substrate ties disposed between the doped region and the set of second transistors.
