    Abstract: Exemplary embodiments are related to digital pre-distortion in envelope tracking systems. A device may include an amplitude modulation-to-phase modulation (AM-PM) distortion unit configured to generate an AM-PM distortion component in response to receipt of phase data of an input transmit signal. The device may also include a local oscillator (LO) path coupled to the distortion unit and configured to convey a local oscillator (LO) signal that varies based on the AM-PM distortion component.

    Abstract: An inductor structure has a first terminal and a second terminal, and includes a conductor path between the first terminal and the second terminal. The conductor path includes a first inductor, a second inductor, a third inductor, a fourth inductor, a fifth inductor, and a sixth inductor. The conductor path may be configured such that, when a current flows from the first terminal to the second terminal, the current flows in a first direction in the first inductor, the third inductor, and the fifth inductor, and the current flows in a second direction in the second inductor, the fourth inductor, and the sixth inductor. The first direction may be clockwise and the second direction may be counterclockwise, or vice versa.
