“…In ultrawideband LNA, 22 the output noise of main noise source is get cancelled by adding the two signal at the output, and this type of noise cancellation technique improves the gain and noise performance of the LNA with the same power consumption. The LNAs in Díaz-Chinea et al and Nauta et al 23,24 explain the noise cancellation of CG transistor with the help of CG-CS configuration. In addition with gain and NF, the proposed feedforward distortion cancellation path reduces the distortions and improves the linearity.…”

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.
