ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper presents a high-Q MWCNT (Multi Wall Carbon Nano-Tube) network based pulse-shaped on-chip embedded nano-inductor for power electronic circuits. This high-Q inductor is fabricated using a composite of MWCNT (multi Wall Carbon Nano Tube) network and Fe in semiconductor processing environment. A layer of nano composite film (Cu/CoFe2o4) is pat...

acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. the conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. it has been rarely reported in the literature. in leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. herein, we rep...

This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vrms ). The topology integrates a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is coupled to the output directly after the first power processing. With this direct power transfer feature and shari...

In current trend for portable wireless communication applications, we require high Q on-chip inductors. In this paper an on-chip 3-D spiral inductor is proposed. High quality factor is achieved by reducing oxide capacitance between substrate and conductor considering permittivity of a substrate. Losses in the structure are reduced by considering high conductivity material like copper or gold. I...

An easy dc-dc boost converter is unable to give high step-up voltage gains due to the effect of power switches, rectifier diodes, and the equivalent series resistance of inductor and capacitors. In this paper proposes new dc-dc converter to achieve high voltage gain without an extremely high duty ratio. In the proposed converters, two inductors with the same level of inductance are charged in p...

Energy harvesting is an attractive solution to extend system lifetime for internet of everything (IoE) nodes. Ambient light is a common energy source that can be harvested by photovoltaic (PV) cells. However, light intensity varies widely depending on location, ranging from ~10s of lux in dim indoor conditions to ~100klux under direct sunlight. Designing a fully integrated light harvester that ...

Abstract — A circuit technique that reduces switching losses of the pulse-width-modulated boost converter is described. The losses are reduced by using a new switch cell that consists of an inductor, a diode, a capacitor, a main switch, and an auxiliary switch. This technique reduces the reverse-recovery-related losses of the rectifier with the inductor that controls the di/dt rate of the recti...
