摘要:
The invention relates to a digitally adjustable electronic capacitor which can be digitally controlled, tuned in a large capacity range across several magnitudes independently of the voltage available, integrated into circuits and produced economically without requiring the use of monolithic semiconductor crystals. The invention consists of a support and printed conductor levels which are isolated from each other, turned towards each other at a certain angle, preferably 90 °, and within each level have conductive printed conductors which are isolated from each other. A capacitor is configured between the printed conductors of the different levels. A digital electronic control element is assigned to each printed conductor level. The printed conductors of each printed conductor level can be connected independently of each other to an electrode via the digital electronic control element assigned to each printed conductor level. At least two printed conductors situated on different conductor levels are linked to the corresponding electrodes by means of the digital electronic control element. The selected capacitor is available at the level of the electrodes.
