Patent Images
1. A method for signal or power transmission through a circuit arrangement that comprises:
- input terminals;
output terminals;
a coreless transformer having a first winding and a second winding;
a trimming device that is connected to one of the first and second windings and that includes at least one of a variable capacitive component and/or a variable inductive component, the variable capacitive component having an adjustable capacitance and the variable inductive component having an adjustable inductance;
the circuit arrangement having a maximum efficiency frequency (MEF) and a maximum impedance frequency (MIF) that are dependent on a load connected to the output terminals, and on one of capacitance and inductance;
the method comprising;
applying an input signal that has an input frequency to the input terminals; and
adjusting one of the MEF and MIF of the circuit arrangement to differ from the input frequency by less than a given frequency difference by adjusting at least one of the adjustable capacitance and the adjustable inductance.
