This work proposes a novel linearized low noise amplifier (LNA) for X-band applications with flat power gain, low noise performance and enhanced linearity. In this study, a triple-cascode topology with dual-resonant network is utilized and a modified post-distortion network is introduced to improve the linearity. The LNA utilizes a subthreshold auxiliary NMOS transistor to reduce the nonlinearity with low power consumption. In addition, a methodology is proposed to predict the characteristic of the linearity performance of the proposed LNA with modified post-distortion network. With a small increase of 1 mW in power consumption due to the inclusion of the post-distortion network, the input intercept point IIP3 is improved and lies in the range of −3 to +8 dBm over the frequency range from 8 to 12 GHz. Implemented in Global Foundries 130 nm CMOS process, the LNA achieves a peak gain of 18 dB, and a 1.3 dB minimum NF over 8 to 12 GHz. The proposed LNA requires an area of 1.2 mm2 and a power of 18 mW.

The low power consumption devices are frequently focused in design and manufacturing wireless communication system. This paper gives a systematic design of a low noise amplifier for WLAN application aimed to obtain minimum noise figure. The simulation result shows that the noise figure is in the appreciable level (1.67 dB). The maximum gain is greater than 10 dB. These are the predominant requirements of an LNA. Also it posses good stability and the LNA design uses pHEMT for its appreciable noise performance.

This paper describes a layout of a CMOS Low Noise Amplifier for reconfigurable packages which include GPS, GSM Wi-Fi applications. The improvement of a notably linear Radio front-stop, able to function with Galileo and GPS satellite signals suitable for coexisting in a mobile opposed environment for area based offerings, pleasing the fundamental necessities for a mass market product which includes low cost, low footprint, good accuracy, low strength intake and high sensitivity. primarily based on a wideband enter matching, the LNA stages cowl all band of hobby even as reaching a great change-off between excessive gain, low noise parent and coffee electricity intake. The complete simulation analysis of the circuit results in the frequency range of 1.4 GHz to 2 GHz. The noise figure is 1.8 dB at 1.4GHz and rises to 3.4 dB at 2 GHz. The input return and output return losses (S11, S22) of the LNA at a frequency range between 1.4 GHz and 2 GHz are S11= -12 dB, S22 =-44.73 dB at 1.77 GHz and S22 =-26.47 dB at 2 GHz. The overall gain of the LNA (S21) is 13 dB at 1.4025 GHz, 3rd order input intercept point (IIP3) = -3.16 dBm and -1dB compression point is -12.56 dBm. Input Impedance of 50Ω, 3dB Power Bandwidth of 450MHz, and Power Dissipation of 2.7mW at 1.2V power supply.

In this paper we present the design of a fully integrated low noise amplifier for WiMAX standard with AMS 0.35 μm CMOS process. This LNA is designed to cover the frequency range for licensed and unlicensed bands of the WiMAX 2.3–5.9 GHz. The proposed amplifier achieves a wide band input and output matching with S11 and S22 lower than -10 dB, a flat gain of 12 dB and a noise figure around 3.5 dB for the entire band and from the upper to the higher frequencies. The presented wide band LNA employs a Chebyshev filter for input matching and an inductive shunt feedback for output matching with a bias current of 15 mA and a supply voltage of 2.5 V.

The paper presents development results for a photodetector module with an integrated lownoise amplifier. The photodetector is based on a commercial indium-phosphide photodiode and a custom-designed adapter board and allows to use an optical carrier with wavelengths of 1.31 and 1.55 μm and performs optoelectronic conversion for electrical signals into 0–50 GHz range. The developed gallium arsenide low-noise amplifier is used to compensate photodiode conversion loss in the X-band frequency range. The photodetector module is intended for use as a microwave photonic link receiver, which provides a significant extension of the signal transmission range in comparison with classical types of transmission lines
