Abstract EN
In recent years, many articles came out where one could find the analysis of oscillatory systems of electric sinusoid signals generators with amplifiers called CFOA—current feedback operational amplifiers.
As a rule, the analysis of such systems is made by applying mathematical modeling methods on the basis of the amplifier linear model, which does not allow estimating advantages and disadvantages of the systems realized with those amplifiers in comparison with classical systems.
A nonlinear model of a current feedback operational amplifier (CFOA) is introduced in the paper; nonlinearity of “current mirror” is reflected in the form of current double limiting.
The analysis of two known oscillatory systems has been carried out with the use of this non-linear model.
Dependence between current limiting level, output voltage amplitude, and maximum oscillation frequency has been obtained.
The paper shows that output current limiting under current output connection of capacitive load reduces frequency range and output voltage amplitude considerably and increases harmonic distortions in comparison with classical oscillatory systems.
The research done has found that the application of new amplifiers does not give considerable advantages to the oscillatory systems with CFOA.
