On the simulation of analog VLSI systems operating in the subthreshold and transition regions

摘要

Issues related to the simulation of analog integrated systems are investigated, especially those utilizing MOSFETs in the subthreshold region. Simulation program with IC emphasis SPICE3, CAzM, and anaLOG, three of the most commonly available university tools, are examined to determine their relative strengths and applicability. The ease of obtaining convergence, the reliability of results, and modeling issues are discussed.
