A methodology is presented for generating compact models of substrate noise injection in complex logic networks. For a given gate library, the injection patterns associated with a gate and an input transition scheme are accurately evaluated using device-level simulation. Assuming spatial independence of all noise generating devices, the cumulative switching noise resulting from all injection patterns is efficiently computed using a gate-level event-driven simulator. The resulting injected signal is then sampled and translated into an energy spectrum which accounts for fundamental frequencies as well as glitch energy. Preliminary results demonstrate the validity of the assumptions and the accuracy of the approach on a set of standard benchmark circuits.

We present an accurate and unified MOSFET model with benchmark test results for analog/digital circuit simulation. The results show that the model can pass most benchmarks suggested for a model used in circuit simulation by SEMATECH recently, and ensures good scalability and accuracy. The model has been implemented in HSpice, Spectre, SmartSpice and Spice3e2.
For advanced submicron VLSI technologies maintaining higher performance and better yield is a challenging task. Layout optimization for improving yield may affect the circuit performance and vice versa. We analyze the...

By artificially introducing a time delay into the desired tip trajectory of a flexible arm it is possible to obtain an open-loop computed torque profile, which is almost causal. The authors show that using the concept of elastic wave propagation one can easily calculate a lower limit on the above time delay.

Two piezoelectric sensor effectiveness coefficients that provide a quantitative measure of effectiveness for piezoelectric materials which are being used for sensing strain (voltage sensor), or strain-rate (current sensor) are introduced. The use of these coefficients for selecting sensor materials is illustrated through a numerical example.

The nondimensional groups which characterize dynamically equivalent single flexible link (SFL) manipulators are determined using the Buckingham Pi method of dimensional analysis. Scaling laws for continuous-time and discrete-time linear rational controllers are developed for dynamically equivalent SFL systems. These theoretical scaling laws are verified experimentally for a discrete PD control law.
