Unformatted text preview: Constant Voltage Scaling Constant Voltage Scaling • Introduction – Shrinks the transistor dimensions linearly – Leaves the applied voltage constant • Positives – Speed increases quadratically – Packing density increases quadratically • Negatives – Electric field increases by same factor used to scale transistor dimensions – Degradation of device performance and reliability at high fields. – Power density (heat dissipation) increases as cubically Constant Voltage Scaling A mix of constant voltage and constant field scaling has been used Challenges to Sustain Scaling http://public.itrs.net/ ITRS: International Technology Roadmap for Semiconductors ITRS2005: Process Integration, Devices, and Structures (PIDS)...
