1. Receiver comprisinga tuning circuit that includes a digitally controlled capacitor bank with n capacitors monolithically integrated in planar form and controlled by a tuning control signal,the n capacitors providing various capacitance values, including a unity capacitor covering a unity IC surface,wherein:

  • capacitors of the n capacitors having capacitance values smaller than the unity capacitor cover respective IC surfaces, which in proportion to their value are smaller than the unity IC surface, andcapacitors of the n capacitors having capacitance values greater than the unity capacitor are formed by clusters of unity capacitors, each unity capacitor covering an IC surface corresponding to the unity IC surface.
