Title: Behavioural VHDL-AMS Model for the Current-Feedback Opera¬tional Amplifier
Keywords: Analog circuits, Current-feedback operational amplifier, Analog simulation, VHDL-AMS
Abstract: In this paper linear, frequency-dependent VHDL-AMS model for the Current-Feedback Operational Amplifier (CFOA) is introduced. The model simulates the actual performance of typical CFOAs for a wide range of frequencies. For creating the model, simplification and build-up techniques known from macromodelling operational amplifiers have been adapted. Model parameters are extracted for the CFOA AD8001 from Analog Devices as an example. To confirm the validity, the simulation results are compared with the manufacturer’s data and with the results obtained by simulation of the PSpice macromodel supplied from Analog Devices.
