Variation Tolerant Energy Efficient Design For Ultra Low Voltage Digital Circuits, Preyom Dey
Electrical and Computer Engineering ETDs
The demand of extremely long battery life for electronic devices is the driving force for modern semiconductor industry in recent years. Supply voltage scaling offers a promising solution for this matter. To control the energy consumption and limit the power dissipation of a circuit, supply voltage should be scaled continually. Threshold voltage should also be reduced to sustain performance and reliability. This scaling of supply and threshold voltage imposes several bottlenecks in ultra-low voltage circuit design. One of the major barriers for ultra-low voltage design is the performance deviation of digital circuit due to supply voltage variation. As technology scales, …
