Abstract
The present disclosure relates to planar transformers including a plurality of circuit layers that are configured to reduce termination losses on at least one of the plurality of circuit layers. The plurality of circuit layers are stacked together in a first direction and include at least first and second circuit layers. The first and second circuit layers each include an electrically conductive trace forming at least one winding having a first termination portion and a second termination portion that are separated by a gap. The gaps of the first and second circuit layers are offset relative to each other in a second direction different from the first direction. The plurality of circuit layers may further include a third circuit layer, which includes an electrically conductive trace having a grounded portion that is disposed adjacent to at least one of the gaps of the first and second circuit layers.
