Abstract: Embodiments disclosed herein relate to impedance matching for outputting wide-band signals in radio frequency applications. In an example, a circuit including a low-noise amplifier (LNA) sub-circuit and a tuning sub-circuit is provided. The LNA sub-circuit is configured to couple to an antenna and includes a transistor that includes a gate, a source, and a drain, a first inductor that includes a first terminal configured to couple to the antenna and includes a second terminal, a second inductor that includes a first terminal coupled to the first terminal of the first inductor and includes a second terminal coupled to the gate of the transistor, and a third inductor that includes a first terminal coupled to the source of the transistor and includes a second terminal. The tuning sub-circuit is coupled to the source of the transistor.
