Absrmct-A physically based, large signal HBT model is presented to account for the time dependence of the base, collector, and emitter charging currents, as well as self heating effects. The model tracks device performance over eight decades of current. As such, the model can be used as the basis of SPICE modeling approximations, and to this end, examples are presented. A thesis for the diverge...

Rapid energy-delay exploration methodology based on circuit sizing as applied to clocked storage elements is presented. Circuit delay and energy are modeled using improved RC delay model of a transistor. The accuracy of the model is increased by using Logical Effort setup accounting for input signal slope and extraction of technology dependent parameters. The minimal energy-delay curve is gener...

The demand for powerfiil computational niacliines using scaled technologies has brought power dissipation to the forefront. Hence. there is a need to accurate11 niodel power dissipation in such teclmologies where both capacitive and inductive effects are iniportant. In this paper. we accurately model short-circuit power dissipation of an inverter driving an RLC load. A closed fonii expression i...

A 550 kHz CMOS micromechanical bandpass filter, is designed using a parameterized cell library, "NODAS," for schematic representation and behavioral HDL simulation. The filter employs a unique resonator and coupling spring structure implemented in a CMOS-MEMS technology. As an alternative design method, an equivalent SPICE model is derived for the filter. Frequency response around the filter pa...

In this paper, a SPICE model representative for the mode conversion occurring in differential lines affected by imbalance either of the line cross-section and the terminal networks is developed. The model is based on the assumption of weak imbalance and allows approximate prediction of modal quantities, through separate modeling of the contributions due to line and termination imbalance by cont...

Simulation Bits: A SPICE Behavioral Model of Non-Linear Inductors© Sam Ben-Yaakov and Mor Mordechai Peretz SPICE simulation is already recognized as a viable tool in Power Electronics. Simulation is particularly useful when dealing with a non-linear behavior that cannot be easily handled analytically. Such a case is the analysis of a switching power converter that includes a non-linear inductor...

Spatial processing of sparse, irregular floating-point computation using a single FPGA enables up to an order of magnitude speedup (mean 2.8× speedup) over a conventional microprocessor for the SPICE circuit simulator. We deliver this speedup using a hybrid parallel architecture that spatially implements the heterogeneous forms of parallelism available in SPICE. We decompose SPICE into its thre...
