چکیده

Abstract: The computer-controlled system for low-frequency noise measurements has been presented. All major functions for adequate polarisation of a device under test are programmable providing complete flexibility and automation for biasing. The inherent noise parameters of the main modules are enclosed. The system enables to measure input-output noise relations for BJTs, JFETs, MOSFETs, MESFETs, HEMTs, and, in general, also other two-ports.

Design of an S-band Ultra-low-noise Amplifier with Frequency Band Switching Capability

In this paper, an ultra-low-noise amplifier with frequency band switching capability is designed, simulated and fabricated. The two frequency ranges of this amplifier consist of the 2.4 to 2.5 GHz and 3.1 GHz to 3.15 GHz frequency bands. The designed amplifier has a noise figure of less than 1dB, a minimum gain of 23 dB and a VSWR of less than 2 in the whole frequency band. The design process s...

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...

Outage Probability Bound and Diversity Gain for Ultra-Wideband Multiple-Access Relay Channels with Correlated Noises

In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

Effect of Underwater Ambient Noise on Quadraphase Phase-shift Keying Acoustic Sensor Network Links in Extremely Low Frequency Band

This study evaluates the impact of underwater ambient noise using seven real noise samples; Dolphin, Rain, Ferry, Sonar, Bubbles, Lightning, and Outboard Motor in three frequency ranges in extremely low frequency (ELF) band. The ELF band is the most significant bandwidth for underwater long-range communication. ELF band which is extended from 3 to 3000 Hz clearly, faces bandwidth limitation. Me...
