    摘要: In various embodiments, apparatuses and methods are disclosed that may be able to implement a multi-layer, three dimensional routing between a decoupling component and an input port for a SoC or MCM. A three dimensional (3D) structure may provide a defined current return path from the decoupling component to the input port. The current return path may be constrained by design to provide an equal and opposite electromagnetic flux to the input port thereby reducing series inductance between the input port and the decoupling component.

    摘要: Various embodiments are directed to apparatuses and methods to reduce average power dissipation in transceiver stages such as power amplifiers and low noise amplifiers (LNAs) that process signals of varying output amplitudes. Power dissipation may be reduced by varying the supply voltage in sympathy with the amplitude of the signal and/or the stage current density which may also be varied in sympathy with the signal amplitude.
