Analysis of low-voltage mixed-signal circuits under device variations

Aggressive supply voltage scaling has become the most effective way to reduce power dissipation in today's mobile battery-powered electronic circuits. However, extreme sensitivity to device variations in low-voltage electronics has made design of such systems extremely complicated. In this paper, a new analytical model for device variations is derived. Based on the new model, the impact of device variations on low-voltage analog and digital circuits in a projected 22nm process technology is investigated.
