Abstract:
1. A transformer comprising: a first dielectric layer; a first coil disposed in a first conductive layer on a first side of the first dielectric layer, the first coil comprising a first end disposed inside the first coil, and a second end disposed at an outer perimeter of the first coil; a second coil disposed in a second conductive layer on a second side of the first dielectric layer, the second side opposite the first side, the second coil comprising a first end disposed inside the second coil, and a second end disposed at an outer perimeter of the second coil; a first crossover disposed in the second conductive layer, the first crossover directly connected to the first end of the first coil and extending past the outer perimeter of the first coil; and a second crossover disposed in the first conductive layer, the second crossover directly connected to the first end of the second coil and extending past the outer perimeter of the second coil.
