Patent ID: 7443264

Claim:
An impedance transformation circuit with a first contact pad and a second contact pad being spaced-apart and formed on a substrate, comprising: at least a first circuit element providing a contact area formed on the substrate and being arranged adjacent and between the first and the second contact pad, a first wire element extending over the substrate connecting the first contact pad and a first end portion of the contact area of the first circuit element, at least a second wire element extending over the substrate connecting the second contact pad and a second end portion of the contact area of the first circuit element, wherein the contact area of the first circuit element is shaped to provide a capacitive connection with a predetermined capacitance between the contact area and a fixed reference potential, and a second circuit element located on the substrate and having a first terminal and a second terminal, the second circuit element having a predetermined capacitance value and being arranged to provide a capacitive connection between the first contact pad and the second contact pad, wherein the first terminal is connected to the first contact pad and the second terminal is connected to the second contact pad.
