Determination of Permeability from Impedance Measurement Using Vector Network Analyzer
This study treats the optimised one-port (reflection coefficient) and two-port (shunt-through/series-through) measurement methods for complex permeability determination of solid soft magnetic materials using a vector network analyzer (VNA) at frequencies from 9 kHz to 6.5 GHz. The principle of measurement methods, the relationships of measured phasor voltage ratio (Sparameter) to complex impeda...
متن کاملArchitectural Solutions Towards a 1,000 Channel Ultra- Wideband WDM Network
In this paper architectural considerations for deployment of ultra-wideband (14501650 nm) WDM networks having a massive number of WDM channels (400-1,000), are presented. The fundamental networking building block is an all-optical ring comprised by ultra-wideband WDM Passive Optical Networks (PONs) interconnected via a suitable optical cross-connect. Each PON could aggregate traffic from hundre...
متن کاملA 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...
متن کاملA Transformer Noise-Canceling Ultra-Wideband CMOS Low-Noise Amplifier
Previously reported wideband CMOS low-noise amplifiers (LNAs) have difficulty in achieving both wideband input impedance matching and low noise performance at low power consumption and low supply voltage. We present a transformer noise-canceling wideband CMOS LNA based on a common-gate topology. The transformer, composed of the input and shunt-peaking inductors, partly cancels the noise origina...
متن کاملWideband and Ultra-Wideband Channel Measurement and Modeling for Broadband Wireless Systems
The spatial domain information of the propagation is extremely important to take into account the antenna systems in the wireless broadband systems. This paper describes the concept and the modeling of the double-directional spatio-temporal channel for wideband and ultra-wideband wireless systems. The research activities toward the establishment of the channel model in Tokyo Tech are also descr...
