Abstract
An embodiment of a transformer-based system or galvanic isolation device includes a first coil, a second coil aligned with the first coil across a gap, and a first capacitor coupled between the first coil and a first voltage reference. A first electrode of the first capacitor may be formed from a conductive electrode structure that is electrically isolated from the first coil, and a second electrode of the first capacitor may be formed from at least a portion of the first coil. The system or device also may include a second capacitor coupled between the second coil and a second voltage reference. The first and second coils may form portions of first and second IC die, respectively, and the system or device may also include one or more dielectric components within the gap between the IC die, where the dielectric component(s) are positioned directly between the first and second coils.
