Abstract
There is disclosed a circuit and method for converting on/off logic signals from one medium to on/off signals useful in a different medium. The circuit is particularly adapted to translate from negative voltage levels to positive voltage levels. The circuit includes voltage control levels for precisely controlling voltage as a function of temperature, all while only using positive voltage levels on the conversion circuit.
