“…However, energy dissipation due to interconnected primitives has limited improvements in operating frequency. Conventional CMOS does waste energy, and has been shown to be lossy [146], due to the heat dissipation at each logic transition. Adiabatic logic is a CMOS design paradigm where the current flow through the circuit is controlled such that the energy is recycled rather than dissipated since the input and output charges are kept separate [147].…”

To my parents, Alfred and Kathleen Morrison, and to my grandparents, Arthur and Betty Kempf, and Alfred and Dorothy Morrison, for making all the opportunities I have possible. ACKNOWLEDGMENTS I would like to thank my advisor, Dr. Nagarajan Ranganathan, for giving me the opportunity to pursue my research, and for his valuable guidance and assistance over these last four years. Ranga has always been an excellent motivator, guider, and leader, and completion of this project would not have been possible without his patience and belief in my ideas. I want to

“…In order to validate the analysis above, the numerical calculation was carried out as follows. For the given area A, the wire thickness t, the distance d, the resistivity ρ and the relative dielectric constant r , the stub length is decided for a given frequency f from eqn (5). The stub width w is decided by eqn (6).…”

This paper compares a stub and a decoupling capacitor for power supply noise reduction. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply bounce of the designed frequency. The conditions where the stub is more effective than the same-area decoupling capacitor are clarified. The stub will work more efficiently and on-chip integration will be possible on high frequency operation LSIs.

“…The research described in [17] considers line inductance, however, the optimization criteria minimize delay using an unrealistic inductance model and do not consider power dissipation. The work described in [20]- [22] considers dynamic power dissipation while ignoring the short-circuit power of the load gate. The work described in [14], [15] considers power dissipation while ignoring the inductive behavior of the interconnect and, therefore, the effect of line inductance on the power characteristics.…”

The width of an interconnect line affects the total power consumed by a circuit. The effect of wire sizing on the power characteristics of an inductive interconnect line is presented in this paper. The matching condition between the driver and the load affects the power consumption since the short-circuit power dissipation may decrease and the dynamic power will increase with wider lines. A tradeoff, therefore, exists between short-circuit and dynamic power in inductive interconnects. The short-circuit power increases with wider linewidths only if the line is underdriven. The power characteristics of inductive interconnects therefore may have a great influence on wire sizing optimization techniques. An analytic solution of the transition time of a signal propagating along an inductive interconnect with an error of less than 15% is presented. The solution is useful in wire sizing synthesis techniques to decrease the overall power dissipation. The optimum linewidth that minimizes the total transient power dissipation is determined. An analytic solution for the optimum width with an error of less than 6% is presented. For a specific set of line parameters and resistivities, a reduction in power approaching 80% is achieved as compared to the minimum wire width. Considering the driver size in the design process, the optimum wire and driver size that minimizes the total transient power is also determined.Index Terms-Characteristic impedance, dynamic power, inductive interconnect, short-circuit power, transient power dissipation, underdamped systems.
