However, even in nonportable systems such as scientific workstations, power is still a serious constraint due to limits on heat dissipation. One design technique that promises substantial power reduction is voltage scaling. The term "voltage scaling" refers to the trade-off of supply voltage against circuit area and other CMOS device parameters to achieve reduced power dissipation while maintaining circuit performance. The dominant source of power dissipation in a conventional CMOS circuit is due to the char..
