On visiting a high-performance GaAs fab, I was shown a problem with the measurement system. The on-wafer test system was calibrated using a power meter and on-wafer standards, using the built-in ...

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

When used with other blocks and modules, a new approach to modeling operational-amplifier output impedance behavior can provide a more realistic overall behavioral model. Simulating the behavior of a ...
