SPICE DEVICE MODELS AND DESIGN SIMULATION EXAMPLES …

APPENDIX BSPICE DEVICE MODELS AND DESIGNSIMULATION EXAMPLES USING PSPICEAND MULTISIMI ntroductionThis appendix is concerned with the very important topic of using PSpice and Multisim tosimulate the operation of electronic circuits. The need for and the role of computer simulationin circuit DESIGN was described in the preface. The appendix has three sections: Section a brief description of the MODELS that SPICE uses to describe the operation of opamps, diodes, MOSFETs, and BJTs. Section presents DESIGN and SIMULATION examplesusing PSpice. Finally, DESIGN and SIMULATION EXAMPLES utilizing Multisim are presented inSection The EXAMPLES are keyed to the book chapters and are numbered in a way thatmakes this relationship transparent.

OS are, respectively, the input bias current and the input offset current specified by the op-amp manufacturer. 3. Common-Mode Input Resistance (Ricm). If the two input terminals of an op amp are tied together and the input resistance (to ground) is measured, the result is the common-mode input resistance R icm. In the macromodel of Fig. B.2 ...
