Research ArticleOpen accessIn the abstractA Fully Integrated Dual-Band Low Noise Amplifier for IEEE 802.11 and Hiper LAN ApplicationMow Shouxian, Ma Jianguo, Yeo Kiat Seng, Do Manh AnhA fully-integrated dual-band Low Noise Amplifier (LNA), which can be used for IEEE 802.11 and Hiper LAN applications, was investigated in this paper. The proposed LAN was implemented entirely pm a single chip based on a standard 0.18 μm 1P6M CMOS process. It draws 13 mA current from a 1.5-V voltage supply and achieves power gains of 17 and 10 … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltra Low Power MUX Based Compressors for Wallace and Dadda Multipliers in Sub-threshold RegimePriya Gupta, Anu Gupta, Abhijit AsatiThe computing efficiency of modern column compression multipliers offers a highly efficient solution to the binary multiplication problem and is well suited for VLSI implementations. The various analyses are established more on compressors circuits particularly with Multiplexer (MUX) design. Conventionally, compressors are anatomized into XOR gate and MUX design. In this study, fully MUX based compressors, utilizing the CMOS transmission … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 17 Nov 2015 · 8,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Interconnect Structure for Elmore Delay Model with Resistance-Capacitance-Conductance SchemeUma Ramadass, Krishnappriya, Jebashini Ponnian, P. DhavachelvanIn this brief, we present a simple close-form delay estimate, based on first and second order moments that handle arbitrary voltages and conductance effects for a lumped and distributed line. This proposed model introduces a simple tractable delay formula by incorporating conductance (G) into Resistance, Capacitance (RC) network by preserving the characteristics of the Elmore delay model. The RCG model … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,045 accessesView PDFCite
