1. A transformer for transforming a differential signal to a single-ended signal, the transformer comprising:

  • a first pair of bonding wires, wherein a first bonding wire of the first pair is connected to the single-ended signal and a second bonding wire of the first pair is coupled to a reference voltage; and

    a second pair of bonding wires carrying a differential current associated with the differential signal, wherein a third bonding wire of the second pair is magnetically coupled to the first bonding wire, a fourth bonding wire of the second pair is magnetically coupled to the second bonding wire, the first and second bonding wires are electrically coupled, and each of the first, second, third, and fourth bonding wires is a single bonding wire partially disposed over silicon.
