Research ArticleOpen accessIn the author namesDESIGN OF HIGH-SPEED PARALLEL IN PARALLEL OUT SHIFT REGISTER USING ALGAAS/GAAS MODFET TECHNOLOGYV. Ganesan, K. S. ShajiThis study enumerates the efficient design and analysis of Parallel In Parallel Out (PIPO) shift register using AlGaAs/GaAs MODFET D Flip-flop. The transient and power analysis are obtained with operating voltage at 1.3 V for the D flip-flop and PIPO shift register using pspice tool. There are many issues facing while integrating many number of transistors like delay, power dissipation, … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 8 May 2014 · 7,152 accessesView PDF Cite

Research ArticleOpen accessIn the author namesNEURO FUZZY BASED PERFORMANCE ANALYSIS OF MULTIBAND ULTRA WIDE BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMG. Joselin Retna Kumar, K. S. ShajiThis study proposes an efficient channel-estimation scheme for Multiband (MB) Orthogonal Frequency Division Multiplexing (OFDM)-based Ultra Wide Band (UWB) communication systems. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. The signal bandwidth in broad band cellular wireless systems typically exceeds the coherence bandwidth of the multipath … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Mar 2014 · 6,624 accessesView PDF Cite
