A wideband low-noise amplifier (LNA) based on the current-reused cascade configuration is proposed. The wideband input-impedance matching was achieved by taking advantage of the resistive shunt-shunt feedback in conjunction with a parallel LC load to make the input network equivalent to two parallel RLC-branches, i.e., a second-order wideband bandpass(More)
A 3.1-10.6-GHz ultra-wideband low-noise amplifier (UWB LNA) with excellent phase linearity property (group-delay-variation is only plusmn16.7 ps across the whole band) using standard 0.13 mum CMOS technology is reported. To achieve high and flat gain and small group-delay-variation at the same time, the inductive peaking technique is adopted in the output(More)
Salinity is one of the major abiotic stresses that impacts plant growth and reduces the productivity of field crops. Compared to field plants, test tube plantlets offer a direct and fast approach to investigate the mechanism of salt tolerance. Here we examined the ultrastructural and physiological responses of potato (Solanum tuberosum L. c.v. "Longshu No.(More)
Ion implantation is a promising technique for fabricating high density bit patterned media (BPM) as it may eliminate the requirement of disk planarization. However, there has not been any notable study on the impact of implantation on BPM fabrication of FePt, particularly at nano-scale, where the lateral straggle of implanted ions may become comparable to(More)
Salinity and drought are two severe abiotic stresses that affect plant growth and decrease food production worldwide. Compared to the field plants, test-tube plantlets could be more direct and fast to investigate the mechanism of stress adaptation. In the present study, the ultrastructural and physiological differences of potato (Solanum tuberosum L. c.v.(More)
Solar energy is indispensable and needs to be developed to meet the future energy demands of the world. One of the impediments to this technology is the low efficiency of the solar module, the glass shield being one of the reasons. At present, solar modules suffer from 4% transmission loss at the air/glass interface (at normal incidence) which increases(More)
In today's rapidly progressing professional world, internet is being used as a medium for almost every operation. Firewalls are extensively implemented to prevent unauthorized access to concealed networks and secure them. Based upon the applied policies a firewall can approve or decline the data packet by scrutinizing them. The large size and intricacy(More)
