Method and apparatus for wide range voltage translation

Abstract:

A method, non-transitory computer readable medium, and circuit for wide range voltage translation using monostable multi-vibrator feedback are disclosed. The circuit includes a bias generation segment and a voltage translator to shift a voltage level of a signal from a first voltage domain of a digital system to a second voltage domain of the digital system. The bias generation segment is configured to detect a voltage range of the second voltage domain and to configure the voltage translator responsive to the voltage range. The voltage translator is configured to directly shift the voltage level of the signal to the second voltage domain. The second voltage domain has voltage levels that are higher than a maximum voltage that can be tolerated by transistors in the digital system.
