An external magnetic field of a few kilogauss is used to alter significantly the radiative properties of the plasmas generated by the capacitive discharge vaporization of thin Ag films. The magnetic field is generated by the plasma current in a large inductor surrounding the plasma. The magnetic field is oriented normal to the electric field in the plasma. This generates a drift motion of the p...

This paper presents the power generation through multiple sources where maximum power point tracking system is used to achieve maximum efficiency. A platform strategy by uniting different kinds of energies was presented by researchers. The dynamic and static performance is theoretically analyzed and design criteria are provided. Due to variations in Dc voltage, the change in wind speed is detec...

A high voltage, variable-frequency driver circuit for powering resonant multipole ion guides is presented. Two key features of this design are (1) the use of integrated circuits in the driver stage and (2) the use a stepper motor for tuning a large variable capacitor in the resonant stage. In the present configuration the available frequency range spans a factor of 2. The actual values of the m...

The synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide a low-loss recirculation path for the induct...

One of the possible techniques to reduces the power consumption in digital CMOS circuits is to slow down the charge transport. This slowdown can be achieved by introducing an inductor in the charging path. Additionally, the inductor can act as an energy storage element, conserving the energy that is normally dissipated during discharging. Together with the parasitic capacitances from the circui...

Among renewable energy sources, solar power has the potential to become one of the main contributors to the future electricity supply. Low voltage photovoltaic systems require a high voltage gain converter for module’s grid connection through a DC-AC inverter. This paper proposes a converter that achieves a high step-up voltage conversion ratio, which contains a coupled inductor, without extrem...

A fully-active low-noise amplifier (LNA) for ultrawideband application is presented. Passive on-chip inductor of conventional LNA design is replaced by low-noise active inductor, significantly reducing the total chip area of the proposed CMOS LNA. The core LNA circuit is a cascoded common-source amplifier loaded with an active inductor. Two buffer stages are used to provide the required input a...

Abstract This paper reports on the fabrication and characterization of high quality factor (Q) copper (Cu) inductors with thick insulator on standard silicon (Si) substrate (ρ = 10–20 cm). The thickness and the area of the insulating layer are optimized for high Q by fabricating inductors on very thick (∼50 μm) embedded silicon dioxide (SiO2) islands and 4–20 μm thick PECVD SiO2 coated standard...
