Multi-path devices with mutual inductance compensation networks and methods thereof

摘要

The embodiments described herein provide compensation for mutual inductance in a multi-path device. In one embodiment, a device includes a multi-path integrated device. The multi-path integrated device includes a first output and a second output. The first output is configured to be coupled to a first output lead through a first bonding wire, and the second output is configured to be coupled to a second output lead through a second bonding wire. Due to their proximity, the second bonding wire has a first mutual inductance with the first bonding wire. A first compensation network is coupled to the first output, and a second compensation network is coupled to the second output. The second compensation network is configured to have a second mutual inductance with the first compensation network. The second mutual inductance at least partially cancels the effects of the first mutual inductance.
