Abstract:
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.
