ABSTRACT:
There is disclosed a converter for converting a floating voltage of a Band Gap Reference voltage generator fabricated in P-substrate CMOS technology to a fixed voltage with respect to ground. The converter of this invention utilizes a subtractor to convert the floating voltage to a fixed reference voltage. In addition, the converter of this invention utilizes two level shifters which are able to level shift the floating voltage down and level shift the shifted down voltage substantially back to the level of the floating voltage in order to allow a buffer to be used prior to the subtractor.
