1. A receiver device for an inductive energy transfer system, the receiver device comprising:

  • a touch sensing device;

    a receiver coil;

    a first capacitor connected in series between the receiver coil and one input terminal of an AC-to-DC converter;

    a second capacitor connected in series between the receiver coil and another input terminal of the AC-to-DC converter, wherein the first and second capacitors are matched to reduce an amount of noise the touch sensing device receives when the receiver coil is receiving energy inductively.
