Abstract: Disclosed herein are signal amplifier architectures that provide a plurality of gain modes. Different gain modes can use different paths through the amplifier architecture. Switches that are used to select the path through the amplifier architecture can be configured to also provide targeted impedance in a degeneration block or matrix. The switches that select the gain path are provided in the amplifier architecture and are thus not needed or used in the degeneration block, thereby reducing the size of the package for the amplifier architecture, improving the noise figure (NF), improving impedance matching, and eliminating the need for control logic associated with the degeneration block or matrix.

Abstract: Disclosed herein are signal amplifiers having a plurality of amplifier cores. Individual amplifier cores can be designed for particular gain modes to enhance particular advantages while reducing other disadvantages. The signal amplifier can then switch between amplifier cores when switching gain modes to achieve desired performance characteristics (e.g., improving noise figure or linearity). Examples of signal amplifiers disclosed herein include amplifier architectures with a high gain amplifier core that reduces the noise figure and a linearity boost amplifier core that increases linearity (e.g., for lower gain modes). The disclosed signal amplifiers have a first active core with amplification chains for each of a plurality of inputs and a second active core with a single amplification chain to amplify signals received at the plurality of inputs.

Abstract: The disclosed technology is related to a radio-frequency (RF) amplifier having a bypass circuit and a resonant structure to improve performance in a bypass mode (e.g., a low gain mode). The disclosed amplifiers have a resonant structure that effectively isolates an amplifier core from a bypass circuit. For example, in a bypass mode, the resonant structure is configured to create an open impedance looking into the amplifier core input. This effectively removes any loading from the amplifier core to the bypass circuit. The disclosed amplifiers with resonant structures improve linearity performance in bypass modes due at least in part to the open impedance to the amplifier core provided by the resonant structure.

Abstract: Described herein are variable gain amplifiers that selectively provide variable or tailored impedances at a degeneration block and/or feedback block depending at least in part on a gain mode of the variable gain amplifier. This advantageously reduces or eliminates performance penalties in one or more gain modes. The variable impedances can be configured to improve linearity of the amplification process in targeted gain modes. The variable gain amplifier can be configured to provide a low-loss bypass mode in a low gain mode to improve signal quality. The degeneration block can be selectively isolated from a reference potential node to improve performance.

Abstract: Low-noise amplifier having programmable-phase gain stage. In some embodiments, a radio-frequency amplifier can include an input node, an output node, and a programmable-phase gain stage implemented between the input node and the output node. The programmable-phase gain stage can be configured to operate in one of a plurality of gain settings, and to provide a desired phase for a signal at each of the plurality of gain settings.
