    Abstract: Omni-band amplifiers supporting multiple band groups are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes at least one gain transistor and a plurality of cascode transistors for a plurality of band groups. Each band group covers a plurality of bands. The gain transistor(s) receive an input radio frequency (RF) signal. The cascode transistors are coupled to the gain transistor(s) and provide an output RF signal for one of the plurality of band groups. In an exemplary design, the gain transistor(s) include a plurality of gain transistors for the plurality of band groups. One gain transistor and one cascode transistor are enabled to amplify the input RF signal and provide the output RF signal for the selected band group. The gain transistors may be coupled to different taps of a single source degeneration inductor or to different source degeneration inductors.

    Abstract: A method and apparatus are disclosed for a configurable mixer capable of operating in a linear, a legacy, and a low-power mode. In the linear mode, the configurable mixer is configured to operate as a double-balanced mixer to multiply a first differential signal by a second differential signal. In the legacy mode, the configurable mixer is configured to as a double-balanced mixer to multiply a differential signal by a single-ended signal. In the low-power mode, the configurable mixer is configured to operate as a single-balanced mixer to multiply a differential signal by a single-ended signal. The operating mode of the configurable mixer may be based, at least in part, on a mode control signal. In some embodiments, the configurable mixer may be included in an analog front end of a wireless communication device.

    Abstract: Multiple-input multiple-output (MIMO) low noise amplifiers (LNAs) supporting carrier aggregation are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes a MIMO LNA having a plurality of gain circuits, a drive circuit, and a plurality of load circuits. The gain circuits receive at least one input radio frequency (RF) signal and provide at least one amplified RF signal. Each gain circuit receives and amplifies one input RF signal and provides one amplified RF signal when the gain circuit is enabled. The at least one input RF signal include transmissions sent on multiple carriers at different frequencies to the wireless device. The drive circuit receives the at least one amplified RF signal and provides at least one drive RF signal. The load circuits receive the at least one drive RF signal and provide at least one output RF signal.
