Abstract : In the ever-growing 5G technology, the millimetre-wave (mmWave) frequency spectrum is the inevitable mainstream for high-speed wireless communication. The wide-ranging spectrum bandwidth of the mmWave frequency attracts interest in radio frequency (RF) front-end design which will be very much beneficial for security and cellular-based applications such as intersatellite communication and automotive vehicle-to-vehicle communication. The RF front end requires low-power and low-noise receiver architecture for effective satellite communication, and it needs high throughput with maximum data transfer for cellular-based applications. To address these challenges, this paper presents a novel low-noise amplifier (LNA) operating from 57.12- to 66.25-GHz frequency. The design is implemented using UMC 65-nm CMOS process technology, and the post-layout simulations are carried out using the Cadence Spectre RF tool. At 60 GHz, the LNA exhibits a power gain of 15.46 dB, minimum noise figure (NF) of 1.32 dB while consuming 6.59 mW from a 1.2-V supply. The LNA employs the current reuse feedforward distortion cancelation technique to improve the third-order input intercept point (IIP3) to +7.258 dBm. The proposed LNA provides a relatively better figure of merit compared to some of the recently proposed mmWave LNA architectures.
