Abstract:
In this paper, an enhanced SPICE macromodel for Current-Feedback Amplifiers
(CFA) is presented which takes into account the second-order effects such as the noise, the commonmode rejection ratio (CMRR), the positive and negative output voltage swing, and power-supply rejection ratio (PSRR) as a function of temperature. The simulation model is developped through modifying the basic macromodel employing the mechanism of controlled sources and subcircuits. Model parameters are extracted for the integrated CFA AD8001 as an example. The accuracy of the model is demonstrated by comparison between the data sheet parameters of the real IC and the simulation results.
