Abstract :
A modification to macromodels for integrated circuit micropower operational amplifiers is presented which involves the addition of an identical power section to each amplifier. The resulting macromodels account for influences of the input signal and load resistance on currents taken from the supply sources. The modelling accuracy of the integrated circuit power consumption is sufficient for typical macromodel applications
