The model shows a voltage transition on a wire called the aggressor, which induces undesirable changes in the voltage at a neighboring wire called the victim. The noise is usually characterized in terms of the peak voltage amplitude induced on a “quiet” victim, and by the delay change associated with the noise effect on a transitioning victim. This latter delay uncertainty effect caused by noise is a primary concern, limiting the 3 Interconnects in ULSI Systems 45 Aggressor Aggressor Victim Fig.
Below some critical dimensions single devices can still be built, but large functional circuits may be difficult to design and manufacture with available techniques. 4 Scaling and Power Dissipation The scaling algorithms also impact on the power consumption of the IC. There are two main sources of power dissipation in a CMOS device: dynamic (or active) switching power in the on state due to the charging and discharging of circuit capacitances, and static dissipation from leakage currents in the off state.
Van Rossum between low power circuits, where power constraints are the main priority, and high-performance circuits allowing for more dissipation. It can be deduced from previous formulas for Pon and Poff that both VDS and VT are important parameters in the setting of the overall power dissipation levels. A lowering of VDS decreases the active power level, but at the same time it will have a deleterious effect on Poff , since VT is limited by VDS for efficient transistor operation . Since lowering the threshold voltage leads to an exponential increase of the off current, it can only occur between narrow margins.
