Abstract
The invention relates to a matching circuit for matching impedance values comprising an impedance element with an impedance value, which corresponds to a required total impedance value of the matching circuit, a structurally determined parasitic unit with a parasitic impedance value and a compensation unit with at least one first compensation element. The first compensation element provides a compensation impedance value which is the dual impedance value of the parasitic impedance value. Furthermore, a system comprising a first circuit unit and a second circuit unit with a matching circuit serving for the matching is provided. Also, a method for the compensation of parasitic units for matching purposes is provided.

A matching circuit for matching an impedance value comprising:
- an impedance element with an impedance value, which corresponds to a required total impedance value of the matching circuit;
- a structurally determined parasitic unit with a parasitic impedance value;
- and
- a compensation unit with at least one first compensation element, wherein the first compensation element provides a compensation impedance value, which is the dual impedance value of the parasitic impedance value,
- wherein the compensation unit provides a second compensation element, and
- wherein the second compensation element provides an impedance value which corresponds to the required total impedance value.
A method for compensating parasitic units for matching purposes with the method steps:
- checking the presence of a parasitic unit in series configuration or in parallel configuration to an impedance element, wherein the impedance element provides a required total impedance value;
- introduction of a compensation unit corresponding to the result of the checking step, wherein:
- in the presence of a parasitic unit in series configuration to the impedance element, the compensation unit is placed in parallel configuration to the series configuration;
- or
- in the presence of a parasitic unit in parallel configuration to the impedance element, the compensation unit is placed in series configuration to the parallel configuration;
- repetition of the checking step;
- and
- repetition of the placing step in the case of a presence of a further parasitic unit.
