ABSTRACT:
A dual sourced voltage supply circuit for use with a flash EPROM or the like and comprising output voltage circuitry including an input for receiving a control signal determining which of two voltage supplies is used to provide an output of the dual sourced voltage supply circuit. The output voltage is provided by one of the two voltage supplies by means of a controllable conductive path connected between one voltage supply and an output node of the circuit. Such controllable conductive path comprises, in series, a first MOSFET transistor connected to the voltage supply and a second MOSFET transistor connected to the output node, both transistors are of the same conductivity type and are arranged to be activated in dependence on the input of the output voltage circuitry; moreover, each transistor has a body connection connected to a respective channel electrode; the body connections are arranged to prevent charge injection occurring between the other channel electrode of the same transistor and the body of the second and first transistor respectively.
