The low noise amplifier is the most important component to compensate the noise figure in a RF front-end module shown in Fig.1. The key design parameters of LNA are the high gain, low noise figure and high linearity. The linearity becomes more and more important in modern digital wireless system because a complex digital modulation where the RF signals usually have high peak-to-average ratio. Therefore a highly linear LNA is demanded in a wireless receiver to reduce inter-modulation distortion. The linearity of LNA is described by its input referred 3 rd order intercept point. Thus, LNA should boost the desired signal power while adding as little noise and distortion as possible so that the retrieval of this signal is possible in subsequent stages in the system [11,12]. Hereby, low noise amplifier should be matched with the antenna characteristics. The characteristics of antenna are excellent input and output matching and high gain. ...

... Its most important function is to offer adequate gain to beat the noise of the subsequent stages. LNA design involves the tradeoff between gain, linearity, NF and power consumption [11,12]. The LNA design optimization technique is used to build tradeoff between gain and linearity [4]. ...
This manuscript deals the RF Front-End Design of Inductorless CMOS LNA Circuit with Noise Cancellation method for IoT Applications. A reconfigurable, Inductorless, wideband, LNA for multi-standard wireless applications among a less-area, single-chip, and RF front-end are presented in this manuscript. In this context the proposed LNA approaches two paths in parallel: CS (common-source) path and CG (common-gate) path. Here CS path is liable for providing adequate gain, at the same time the CG path achieved as the matching of input impedance. In this CG path the noise involvement can be removed by noise cancellation technique consequently, on the whole Noise Figure is enhanced. The mismatch of phase among the 2 different paths is moreover quantitatively investigated with analyze to its effect on NF and gain. The methodical values agreed to fit with their simulation values. The considered LNA designed in a CMOS 45nm technology process. The simulated result with the frequency range of 1.04GHz with bandwidth of 3dB gain has achieved 22 dB gain and a low NF of 1.9 dB. The obtained 1dB compression point (IP1dB) is -22.4dBm and also LNA consumes only 6.5mA with 1.2V power supply.

This article has been withdrawn as part of the withdrawal of the Proceedings of the International Conference on Emerging Trends in Materials Science, Technology and Engineering (ICMSTE2K21). Subsequent to acceptance of these Proceedings papers by the responsible Guest Editors, Dr S. Sakthivel, Dr S. Karthikeyan and Dr I. A. Palani, several serious concerns arose regarding the integrity and veracity of the conference organisation and peer-review process. After a thorough investigation, the peer-review process was confirmed to fall beneath the high standards expected by Materials Today: Proceedings.
The veracity of the conference also remains subject to serious doubt and therefore the entire Proceedings has been withdrawn in order to correct the scholarly record.
