Toward sub 1 V analog integrated circuits in submicron standard CMOS technologies

Lower channel lengths lead to lower supply voltages. For 0.25 /spl mu/m MOSTs the supply voltage is 2.5 V. Even lower supply voltages will follow. This paper deals with analog integrated circuits that can handle the reduction of the supply voltage down to 1 V. Existing solutions for such low supply voltages are: 1) reduction of threshold voltages from 0.7 V to 0.3-0.4 V; 2) use of voltage multipliers. It is possible to reduce supply voltages to 1 V in standard CMOS without voltage multipliers. The advent of deep submicron CMOS dictates reduced supply voltage.
