Abstract:
This paper presents new current feedback amplifier and drive-R – amplifier macromodels at behavioral level. They accurately models basic differentialmode electrical characteristics, the offset input voltage and current, the input voltage noise, the output voltage swing, short-circuit current and the input and output impedances. For creating the model, simplification and build-up techniques known from modeling voltage feedback amplifiers have been adapted. As examples model parameters are extracted for the AD8001 and OPA860 from Analog Devices and Texas Instruments, respectively. To confirm the validity of the proposed macromodels, simulation results are compared with the manufacturer’s data. The proposed behavioral macromodels leads to a low analysis time, with higher accuracy and a better convergence in comparison with other op amps methods of modeling.
