Abstract: Circuits and methods for a radio frequency amplifier, such as an LNA, that include a wideband coupled input impedance matching network. One embodiment includes a first inductor coupled between a first terminal and a first node, the first terminal couplable to a degeneration terminal of an amplifier core; a second inductor coupled between a second terminal and either the first node or a second node, the second terminal couplable to an input terminal of the amplifier core; a third inductor coupled between the first node and a third terminal, the third terminal couplable to a reference potential; and, in a variant embodiment, a fourth inductor coupled between the second node and a fourth terminal, the fourth terminal couplable to the reference potential; wherein the first inductor and the second inductor are mutually coupled. Some embodiments allow multiple modes to allow tradeoffs of gain versus linearity and NF characteristics.

Abstract: Methods and devices addressing design of wideband LNAs with gain modes are disclosed. The disclosed teachings can be used to reconfigure RF receiver front-end to operate in various applications imposing stringent and conflicting requirements. Wideband and narrowband input and output matching with gain modes using a combination of the same hardware and a switching network are also disclosed. The described methods and devices also address carrier aggregation requirements and provide solutions that can be used both in single-mode and split-mode operations.
