Dual sourced voltage supply circuit

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