  • Patent number: 7944299
    Abstract: A method and circuit for changing a threshold voltage of a transistor. The circuit includes a sense circuit coupled to a switching transistor, a circuit transistor and to one terminal of a resistor. The other terminal of the resistor is connected to a body contact. The switching transistor directs current along one of two different paths in response to an input voltage sensed by the sense circuit. When the switching transistor directs a first current along one path, the first current is steered towards the resistor and flows through the resistor in one direction and when the switching transistor directs a second current along the other path, the second current is directed towards the resistor and flows through the resistor in the opposite direction from the first current. Steering the currents varies the potential of a body with respect to the potential at the source of the circuit transistor.
