This paper presents a 2.14GHz RF front end for Wide-band Code Division Multiple Access (WCDMA) receiver. The receiver is based on direct conversion architecture and implements a low noise amplifier (LNA) and a quadrature mixer in 0.25μm CMOS process. The receiver achieves a noise figure (NF) of 8.93dB, provides a gain of 17.14dB, has an IIP3 of -15.04dB and dissipate 72.15mW at 2.5V.

A two-stage 1.9GHz monolithic low-noise amplifier (LNA) with a measured noise figure of 2.3dB and an associated gain of 15dB was fabricated in a standard silicon bipolar transistor array. It dissipates 5.2mW from a 3V supply including the bias circuitry. Input return loss and isolation are -9dB and -20dB, respectively.

The objective is to develop an amplifier with desired specifications. In this paper we have tried to explain how we designed an amplifier at 2.47 GHz for W-LAN application and had two options. They were whether to design a power amplifier (PA) or to design a low noise amplifier (LNA). The possibility of PA was eliminated by the fact that we were going to use it as the first block in receiver si...

This paper deals with the design of low power low noise neural signal amplifier for Epileptic Seizure Prediction. The advent of Micro-electro Arrays has driven the need for implantable electronic circuitry to detect those Extracellular neural signals (ENG). We proposed a preamplifier of fully differential Low Noise Amplifier (LNA) with gm boosting in order to enhance the gain as well as reduce ...

Low Noise Amplifier (LNA) is one of the essential components in Ultra Wideband (UWB) devices. Conventional LNA suffers from large chip area, high power consumption and inadequate Noise Figure (NF). A compact UWB LNA in the bandwidth of 3.1 to 10.6 GHz is proposed. The design is based on inductor-less configuration using the resistive shunt feedback topology and noise canceling techniques for wi...

Low power wideband noise amplifier is design by using resistive shunt feedback, current reuse, gain flatting techniques, and inductive feedback technique. The high mobility electron transistors are used to improve the Noise Figure (NF) and scattering paramete...

With the advent of cryogenically cooled front-end assemblies, it has become the practice to define antenna system noise temperature at the horn aperture rather than at the low-noise amplifier (LNA) input port. It is not generally known that when the reference port is moved towards the horn aperture, the values of the operating system noise temperature, Top, and effective receiver noise temperat...

A fully-integrated 4.3-7 GHz CMOS low-voltage wideband low-noise amplifier with helical inductors has been demonstrated in this paper. The CMOS LNA, operating at a supply voltage as low as 1 V, achieves a small signal gain of 14 dB and 3-dB bandwidth from 4.3 to 7 GHz. The minimum noise figure is 2.9 dB at 6 GHz. With the benefits of helical inductors, the total effective chip size is only 0.2 mm.

In this paper, a CMOS low-noise amplifier (LNA) with a new input matching topology has been proposed, analyzed and measured. The input matching network is designed through the technique of capacitive feedback matching network. The proposed LNA which is implemented in a 0:18-mm1P6M CMOS technology is operated at the frequency of 12.8GHz. It has a gain S21 of 13.2 dB, a noise figure (NF) of 4.57 ...
