MT-099: Analog Circuit Simulation
In recent years there has been much pressure placed on system designers to verify their designs with computer simulations before committing to actual printed circuit board layouts and hardware. Simulating complex digital designs is extremely beneficial, and very often, the prototype phase can be eliminated entirely. The same is not true for most analog circuits. While simulation can give a grea...
متن کاملCircuit Simulation for Mixedsigna Analog/digital Circuits Analog/digital Circuits Circuit Simulation for Mixed-signal Analogldigital Circuits
The increasing use of mixed signal circuits with analog and digital circuitry on the same lchip have created a set of demands that traditional circuit simuiators cannot meet very well. We pmsent techniques to efficiently handle the simulation of mixed signal analog/digital circuits, a d SYMPHONY , a fast mixed-signal simulator which embodies them. SYMPHONY combines a fast simulator for digital ...
متن کاملNonlinear Circuit Simulation in the Frequency-domain∗
Simulation in the frequency-domain avoids many of the severe problems experienced when trying to use traditional time-domain simulators such as Spice [1] to find the steady-state behavior of analog, RF, and microwave circuits. In particular, frequency-domain simulation eliminates problems from distributed components and high-Q circuits by forgoing a nonlinear differential equation representatio...
متن کاملA Submicron MOSFET Model for Analog Circuit Simulation
Models for analog circuit simulations must achieve good and continuous representation of current through the device over the complete range of modes of operation including saturation and weak, moderate and strong inversion. In addition the drain current and its derivatives must be continuous to avoid convergence problems and give proper description of the transconductance and output conductance...
متن کاملEfficient Reordering for Direct Methods in Analog Circuit Simulation
For linear systems of equations arising from circuit simulation, we studied the efficiency of the reordering algorithm integrated in the MA27 subroutine package from Duff and Reid. Our conclusion is that the algorithm performs extraordinarily well, provided that the nearly-dense rows and columns of the matrix have been removed prior to reordering. Thus, we recommend the reordering implementatio...
