Abstract

Incidence of cryptococcal infection is high in developing countries such as India. Cryptococcal meningitis is the most common, life-threatening, opportunistic, fungal disease in human immunodeficiency virus (HIV)-infected individuals. Pulmonary, intestinal, bone marrow, and retinal involvement have also been described. There are very few reports of cryptococcal lymph node involvement. We report here a case of generalized lymphadenopathy by Cryptococcus neoformans in 37 years old male diagnosed by biopsy and culture of the involved lymph nodes.

Keywords

Abstract

Low Noise Amplifier is considered as one of the most important component at the receiver end. The basic characteristics and features that a device should possess in the field of Wireless Sensor Network is high gain with low power consumption and size as miniaturize as possible. The Carbon Nano Tube Field Effect Transistors (CNTFETs) are being widely studied as possible successors to silicon based CMOSFETs that have a size much smaller than that of the conventional transistors. This paper presents the behavioral modeling and comparative performance interpretations of a Low Noise Amplifier based on CMOSFETs and CNTFETs using Verilog-A hardware description Language.

Keywords

CNTFET, RF-MEMS, Switch, Low Noise Amplifier, Behavioral Modeling, Verilog-A.

Abstract

Objective: The aim of this work is to design a robust and reliable XOR circuit for ultra-low power operation in sub-threshold region. Method/Analysis: Comprehensive simulations have been carried out on SPICE using 16-nm predictive technology model (PTM) to accomplish our objective. Findings: A Schmitt-trigger based approach is employed to alleviate the effect of device threshold (Vt)fluctuation on XOR circuits. The proposed XOR circuit exhibits narrower spread in its design metrics proving its reliability in sub-45nm regime. Novelty/Improvement: This paper also analyzes various existing XOR gates in presence of process and environment (voltage and temperature)fluctuations to validate their performance. The proposed technique offers full voltage swing. Variability of the design metrics (propagation delay and power dissipation) is investigated and several XOR circuits are compared. The proposed Schmitt-trigger based XOR circuit exhibits narrower spread in its design metrics proving its reliability in sub-45nm regime.

Keywords

Abstract

Objective: The objective of this paper is to realize an n-bit reversible number generator. Several designs of number generator and their corresponding constraints with feedback controller and initial state have also been discussed. Method/Analysis: The proposed design is validated by simulating the results in Verilog HDL. Findings: In this paper a design is presented to implement an n bit number generator as a finite state automation, using reversible logic for the implementation of the transition network. A realizable circuit is designed to implement the n-bit number generator using feedback controllers. Novelty/Improvement: With the use of reversible logic, the designed circuit reaches all the possible states and consumes no power.
