    摘要: Described are embodiments of stacked field effect transistor (FET) switch having a plurality of FET devices coupled in series to form an FET device stack. To prevent the FET device stack from being turned on during large signal conditions, one or more decoupling paths are provided and are configured to pass the time-variant input signal during the open state of the FET device stack. The first decoupling path may include a capacitor, a transistor, or the like, that passes the time-variant input signal by, for example, presenting a low impedance to the time-variant input signal during the open state. The decoupling paths may be connected so that the time-variant input signal bypasses a portion of the FET device stack during the open state.

    摘要: In one embodiment, an amplification device has a temperature differential sensing circuit that reduces a local thermal memory effect. The amplification device may include an amplification circuit and biasing circuitry. The amplification device is operable to receive an input signal and generate and amplified output signal. The biasing circuitry generates a biasing signal that sets the quiescent operating level of the amplified output signal. The temperature differential sensing circuit provides a bias level adjustment signal that adjusts the biasing signal to maintain the quiescent operating level of the amplified output signal at a desired level.
