Abstract
An arrangement for reducing interference in tuned circuits in integrated circuits as a result of the reception and transmission of high frequencies. An external tuned circuit is integrated in the integrated circuit and the interference which is otherwise produced by the connecting pins is eliminated.
Claims5
An arrangement for reducing interference in an integrated circuit comprising:
- a mixer,
- an oscillator coupled to the mixer
- a capacitance diode,
- an inductance, and
- a controller coupled to the capacitance diode via a first bond wire which forms a first part of the inductance,
- the capacitance diode being coupled to the oscillator via a bond wire which forms a second part of the inductance.
