Guide to SPICE and the specter of The Designer's TM is an in-depth guide to circuit simulators from a designer's point of view: the trap circuit simulation, such as convergence and accuracy problems, described in terms a circuit designer comfortable with. It also provides practical advice on how to make many difficult measurements with a circuit simulator, such as loop gain of the op-amp or distortion measurements of such clocked circuits d-to-a converter circuits and sample-and-hold. After reading The Designer's Guide to SPICE and the specter of TM, you'll spend less time fighting simulator and more time to explore, understand and design your circuit.
