Method And System For A Pseudo-Differential Low-Noise Amplifier At Ku-Band
Methods and systems for a pseudo-differential low-noise amplifier at Ku-band may comprise a low-noise amplifier (LNA) integrated on a semiconductor die, where the LNA includes first and second differential pair transistors with an embedded inductor tail integrated on the semiconductor die. The embedded inductor tail may include: a first inductor with a first terminal capacitively-coupled to a gate terminal of the first differential pair transistor and a second terminal of the first inductor coupled to second, third, and fourth inductors. The second inductor may be coupled to a source terminal of the first differential pair transistor, the fourth inductor may be coupled to a source terminal of the second differential pair transistor, and the third inductor may be capacitively-coupled to a gate terminal of the second differential pair transistor and also to ground. The second inductor may be embedded within the first inductor.
INTERMODULATION DISTORTION MITIGATION
An electronic device includes one or more antennas and a radio frequency front end (RFFE) that is coupled to the one or more antennas. The RFPE includes a differential circuit and a tail current source. The tail current source includes a transistor with a drain coupled to the differential circuit via a tail node. The tail current source also includes a capacitance coupled between the drain and a gate of the transistor.
