A Modified Noise Analysis of a Common Source ̶ Common Gate Low Noise Transconductance Amplifier for Sub-micron Technologies
This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...
متن کاملDesign of Low Noise Amplifier for Ultra-Wideband Applications
The recent surge in the demand for low power portable wireless electronics that can offer extremely high data rates has resulted in much active research in Ultra-Wideband (UWB) systems. UWB is widely recognized as a promising technology for high data rate, short-range applications with precise time resolution and high energy efficiency. All these benefits originate from the wideband characteris...
متن کاملDesign of High Gain Wideband Low Noise Amplifier based on Matching technique for Multiple Applications
Increasing demands of portable wireless devices have motivated the development of CMOS radio frequency integrated circuits (RFIC). In wireless system Low Noise Amplifier is the first stage of any RF Receiver design. Performance of RF receiver mainly depends on the effectiveness of LNA. The main objective of the LNA design is to get good gain with minimum noise generation for the entire operatin...
متن کاملS-Parameter Comparison of Common Source and Common Gate Low Noise Amplifier
Scattering Parameters or S-parameters are complex numbers which tells us about how voltage waves are propagating in the radio-frequency (RF) environment. In this paper common source and other will be the cascoded common gate topologies have been analyzed. Scattering parameter analysis shows that gain and impedance matching is better for CG LNA. S-parameter is an important tool for LNA design, f...
متن کاملAnalysis and Design of Wideband Low Noise Amplifier with Digital Control
The design issues in designing low noise amplifier (LNA) for Software-Defined-Radio (SDR) are reviewed. An inductor-less wideband low noise amplifier aiming at low frequency band (0.2-2 GHz) for Software-DefinedRadio is presented. Shunt-shunt LNA with active feedback is used as the first stage which is carefully optimized for low noise and wide band applications. A digitally controlled second s...
