N2 - This paper presents a transformer-based improved multi-path noise-canceling (IMNC) low noise amplifier (LNA) for K-band satellite communications. The design enhances the dual-path noise cancellation and significantly reduces the noise figure. The proposed LNA employs a three-coil transformer with dual-eight-shaped inductor to boost gain, and introduces a noise cancellation path for the common-gate transistor to optimizes noise performance. During the circuit design phase, a multicomponent integrated modeling (MIM) technique is applied, which accurately characterizes the EM field of the LNA and ensures high consistency between simulation and measurement results. The LNA, fabricated in a 40 nm CMOS process, consumes 28.8 mW of power and achieves a peak gain of 12.6 dB. Its 3-dB bandwidth ranges from 19.9 to 25 GHz with a minimum noise figure of 2 dB. The core area of the LNA is 0.16
