HYBRID TRANSFORMER STRUCTURE ON SEMICONDUCTOR DEVICES

摘要

Several novel features pertain to a hybrid transformer formed within a semiconductor die having multiple layers. The hybrid transformer includes a first set of windings (702) positioned on a first layer of the die. The first layer is positioned above a substrate of the die. The first set of windings includes a first port (706) and a second port (708). The first set of windings is arranged to operate as a first inductor. The hybrid transformer includes a second set of windings (704) positioned on a second layer of the die. The second layer is positioned above the substrate. The second set of windings includes a third port (710), a fourth port (712) and a fifth port (714). The second set of windings is arranged to operate as a second inductor and a third inductor. The first set of windings and the second set of windings are arranged to operate as a vertical coupling hybrid transformer.
