ABSTRACT:
A digital circuit with a 5 V power supply voltage in which NMOS transistors constructed in sub-micron technology are protected against excessive field strengths by means of additional transistors in order to prevent so-called "hot carrier stress" for this purpose the additional transistors have a greater channel length and/or a higher threshold voltage.
