Patent ID: 7378898

Claim:
A four terminal electronic circuit, comprising: A power transistor device, with a conduction channel node connecting to a first power supply node, and another conduction channel terminal connecting to a second power supply node; A first sub-circuit, supplying a body bias determined by a desired operational state to a body node of the power transistor device; A second sub-circuit, supplying a drive input signal determined by said desired operational state to a first control gate of the power transistor device; A third sub-circuit, supplying a voltage bias to the first control gate of the power transistor device wherein said voltage bias is equal to or slightly greater than a conduction threshold voltage of the power transistor device; A capacitor, of capacitance suitable for power supply decoupling, with one of its terminal nodes connecting to the first power supply node and the other to a ground node; A first input signal, of a binary nature, that simultaneously changes the outputs of the first and second sub-circuits, such that the bias difference between the source node and the body node of the power transistor device changes polarity, and the drive input signal changes so as to substantially change the conduction condition of the power transistor device; And a common, monolithic semiconductor substrate integrating the power transistor device, the first sub-circuit, the second sub-circuit and the third sub-circuit.
