Frequency filtering or selection circuit for HF signal reception and/or generation incorporated in IC metallisation with constant ohmic resistance

摘要

The circuit (100) has at least 2 oscillation circuits (10,20,30), each provided with at least one inductive element (12,22,32) and at least one capacitive element (14,24,34), the inductive elements magnetically coupled together. At least part of the circuit is incorporated in an IC metallisation (40) with a constant ohmic resistance. An independent claim for an IC with at least one frequency filtering and/or selection circuit is also included.
