Abstract
Methods and apparatus provide for enabling a digital circuit by biasing at least one switch transistor ON such that a voltage potential of a virtual ground node is substantially equal to a voltage potential of a ground node for a power supply to the digital circuit, wherein the digital circuit is implemented using a plurality of transistors in a silicon-on-insulator (SOI) arrangement and at least some of the transistors are referenced to the virtual ground node; and disabling the digital circuit by biasing a gate terminal of the switch transistor below the voltage potential of the ground node.
