Current trends in VLSI processing is pushing towards the use of lower on chip power supplies. For example: the evolution from a UDR75 (150 A gate oxide) to the CDRl (9OA gate oxide), or CDR2 (70 A gate oxide) process has forced us to go from a 5V supply to a 3V supply. Eventually when the gate oxide reaches the 20A range the maximum on chip supply will be 0.9V.
