2. 1. Low-Power Multi-GHz Circuit Techniques for On-chip Clocking

   Author : Martin Hansson; Atila Alvandpour; Per Larsson-Edefors; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; low-power; high-performance; flip-flop; clocking; leakage-compensation; process-variation; Electronics; Elektronik;

   Abstract : The impressive evolution of modern high-performance microprocessors have resulted in chips with over one billion transistors as well as multi-GHz clock frequencies. As the silicon integrated circuit industry moves further into the nanometer regime, three of the main challenges to overcome in order for continuing CMOS technology scaling are; growing standby power dissipation, increasing variations in process parameters, and increasing power dissipation due to growing clock load and circuit complexity.
