Original Abstract

This paper describes the practical results of the performance of the digital potentiometers in comparison with Spice-based macromodel for frequencies of several MHz. Verification and validation checks have been performed on the new Spice compatible macromodel developed on the basis of extensive testing of the behavior models from different reputable companies such as Maxim, Analog Devices, Intersil, etc. The real system performance conditions are tested on programmable universal active filter. Subsequently the possibilities of using chain structure are tested and a digital potentiometer with high resolution and applicable to frequencies exceeding 1MHz frequency band is created. Finally, the control software is introduced.
