ABSTRACT:
A level shifter for low voltage operation includes two level shifting stages. The first stage shifts the input voltage level to an intermediate voltage level, and the second stage shifts the intermediate voltage level to an output voltage level. This two-stage arrangement allows the level shifter to function for very low input voltages, and enables functionality across a wide range of output voltages. The first stage is designed to be compatible with very low input voltages and the intermediate voltage level is chosen to be within the safe operating limits of the first stage. The intermediate voltage level is also high enough to drive the high voltage devices of the second stage. This level shifter can be used where multiple output voltage levels are required depending on the particular application or operating mode.
