Abstract :
A complete model for the Operational Transconductance Amplifier (OTA) is presented. The model includes the transconductance frequency response, the input bias current to output current transfer function, as well as the dependence of both input and output impedances on input bias current. This model is suitable for being included in complex simulation macromodels or for use in analytical calculations. Simulation results and comparisons are also presented
