  • MULTI-PATH DEVICES WITH MUTUAL INDUCTANCE COMPENSATION NETWORKS AND METHODS THEREOF
    Publication number: 20150263681
    Abstract: 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.

  • Amplifier using nonlinear drivers
    Patent number: 8952758
    Abstract: A device includes a Doherty amplifier having a main path and a peaking path. The Doherty amplifier includes a main amplifier configured to amplify a signal received from the main path and a peaking amplifier configured to amplify a signal received from the peaking path when the signal received from the peaking path exceeds a predetermined threshold. The device includes a first driver amplifier connected to the main path of the Doherty amplifier. The first driver amplifier is configured to exhibit an amplitude and phase distortion characteristic that is an inverse of an amplitude and phase distortion characteristic of the main amplifier. The device includes a second driver amplifier connected to the peaking path of the Doherty amplifier. The second driver amplifier is configured to exhibit an amplitude and phase distortion characteristic that is an inverse of an amplitude and phase distortion characteristic of the peaking amplifier.
