CMOS LEVEL SHIFTER WITH FEEDFORWARD CONTROL TO PREVENT LATCHING IN A WRONG LOGIC STATE

A level shift circuit provided with feedforward control to keep the circuit from latching in a wrong logic state comprises a pair of input transistors acted as a differential amplifier and a pair of output hold transistors coupled to output nodes of the circuit. The feedforward control is performed by a pair of feedforward transistors respectively coupled in parallel to the corresponding output hold transistors, and by a pair of isolation transistors that isolate the output nodes from gates of the respective feedforward transistors.
