A current-feedback amplifier macromodel has been developed which simulates the more common small-signal effects such as small-signal transient response and frequency response as well as temperature effects, noise, and power supply rejection ratio. Also modeled are large-signal effects such as non-linear input transfer characteristics and input/ output slew rate limiting.

Detailed descriptions of each stage in the model will be presented with examples of model performance and correlation to actual device behavior.
