High speed hardware designSECTION 7 HIGH SPEED HARDWARE DESIGN TECHNIQUES Walt Kester, James Bryant, Walt Jung, Adolfo Garcia, John McDonald, Joe Buxton ANALOG CIRCUIT SIMULATION Walt Kester, Joe Buxton 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. However, bypassing the prototype phase in high-speed/high-performance analog or mixedsignal circuit designs can be risky for a number of reasons. For the purposes of this discussion, an analog circuit is any circuit which uses ICs such as op amps, instrumentation amps, programmable gain amps (PGAs), volt……
