Originální abstrakt

The practical performance results of digital potentiometers compared with Spice-based macro model at frequencies above 1 MHz are discussed in the paper. Verification and validation checks have been performed on the new Spice compatible macromodel developed on the basis of extensive testing of the models behavior from different reputable companies such as Maxim, Analog Devices, Intersil, Texas Instrument, etc. several types of programmable universal active filters. Subsequently the possibilities of using chain structure for the creating of a digital potentiometer with high resolution and applicable to frequencies exceeding 1MHz frequency band are presented. Finally, the control software is introduced.
