1. Receiver comprising a tuning circuit including a digitally controlled capacitor bank with n capacitors being monolithically integrated in planary form and being controlled by a tuning control signal, characterised by said n capacitors providing various capacitance values including a unity capacitor covering a unity IC surface, wherein capacitors having capacitance values smaller than said unity capacitor cover respective IC surfaces, which in proportion to their value are smaller than said unity IC surface and wherein capacitors having capacitance values greater than said unity capacitor are being formed by clusters of capacitors, each covering an IC surface corresponding to said unity IC surface.
