This paper presents a ultra wideband low noise amplifier for 6GHz Applications. This proposed LNA is the extension of inductively common source amplifier and in this design we used transistor multifingering techniques in order to reduce noise and improves gain. This LNA is simulated by using UMC .18um CMOS mixed signal/RF process in cadence virtuoso. In this design, used current source biasing,...

The use of quantitative methods for aquatic plants has not become as standardized as other components in the aquatic ecosystem, such as biotic (e.g., fish) or physical components (e.g., water chemistry) (APHA 1995, Lind 1979, Wetzel and Likens 1991). Even when considering aquatic biomass sampling, which is a widely accepted means of quantifying aquatic plant communities, there is considerable d...

We report a high performance phase modulation direct detection microwave photonic link employing a photonic chip as a frequency discriminator. The photonic chip consists of five optical ring resonators (ORRs) which are fully programmable using thermo-optical tuning. In this discriminator a drop-port response of an ORR is cascaded with a through response of another ORR to yield a linear phase mo...

In this paper, a summary of our work in the area of tunable microwave circuits based on thin film ferroelectrics is presented. First, a technique is introduced to improve the linearity of thin film ferroelectric tunable capacitors. Measurements show an improvement in the 3rd order intermodulation point at the input (IIP3) of 16 dB. Next, the design and fabrication of an impedance tuner employin...

In this paper, a lattice network-based second-order all-pass filter (APF) design is presented. Unlike previously published works, floating active inductors (FAIs) are used in the topology. Inductance (L) and quality factor (Q) tunability of Q-enhanced FAIs employed to ensure designed APF robust process-voltage-temperature (PVT) variations make filter’s group delay responses constant for wide fr...

Delivering high gain, low noise and good linearity simultaneously with low power consumption in fully-integrated CMOS low noise amplifiers (LNAs) has posed significant difficulty. This paper presents a 19 dB gain, 2.4 dB noise figure, common-gate common-source (CG-CS) single-ended LNA operating at 5.4 GHz. Using gm-boosting, current-reuse and transformer feedback techniques, the LNA mitigates s...

A VHF (30MHz-300MHz) band digitally programmable low noise amplifier (LNA) has been implemented with a 0.25um standard CMOS process for VHF CMMB mobile TV tuners. Utilizing a T-match input network, input matching of more than a decade bandwidth is achieved across all gain settings. Adopting the multiple gated technique, gain flatness enhancement and capacitor reuse etc., the proposed LNA demons...

We construct a polynomial of degree d in two variables whose Hessian curve has (d − 2) connected components using Viro patchworking. In particular, this implies the existence of a smooth real algebraic surface of degree d in RP 3 whose parabolic curve is smooth and has d(d− 2) connected components. “Salut à toi Che Guevara”

Breast cancer is the most common cancer seen in females throughout the world (DeSantis et al., 2014). The epidemiologic profiles of breast cancer in Asian countries differ from Western countries. (Agarwal et al., 2007; Toi et al., 2010). Age-standardized incidence rates of breast cancer are high in North America and western Europe, moderate in South America and eastern Europe, low in Asia (Shib...
