Bi-directional voltage translator

摘要

A bi-directional voltage translator is disclosed. The bi-directional voltage translator includes a step-up voltage translator for converting signals of a first voltage level to signals of a second voltage level, and a step-down voltage translator for converting signals of the second voltage level to signals of the first voltage level. The step-up voltage translator includes a first source sense circuit, a first block feedback circuit and a first output driver circuit. The step-down voltage translator includes a second source sense circuit, a second block feedback circuit and a second output driver circuit.
