Modeling and performance of on-chip spiral inductors is presented. Y-parameters are obtained from the measured S-parameters of the inductor fabricated in 0.35-μm SOI CMOS technology. Matlab is used to get the π-equivalent circuit model parameters at each frequency point. The SOI CMOS inductor shows better performance characteristics in terms of Q-factor and self-resonance frequency.

A design methodology for minimum volume of LCL filters applied to grid connected converters is proposed. It combines the determination filter parameter values (inductances and capacitances) hardware (component technology inductor construction). Using proposed strategy, different combinations L-C-L that meet standard restrictions are determined. The influence harmonic content results from consid...

We show that the maximum impedance of the parallel combination of a resistor , R an inductor L and capacitor , C studied in a previous paper can be found analytically, without using calculus. In fact, we show that the maximum impedance of this parallel combination is just the value of the resistor R and occurs when the driving frequency  is equal to 1/ . o LC   These results were only demons...

Wave propagation in composite structures with shunted piezoelectric patches is investigated in this work. The Wave Finite Element(WFE) approach is firstly developed as a prediction tool for wave propagation characteristics like dispersion curves in composite structures, and subsequently extended to consider shunted piezoelectric elements through the Diffusion Matrix Model(DMM). A three-layered ...

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...

Easy to use multifunctional wearable devices, with no wires hanging around, are needed for real time health monitoring at user's comfort. Herein, an inductor-capacitor (LC) resonant tank-based wireless pressure sensor, screen-printed on electrospun Poly-L-lactide (PLLA) nanofibers-based flexible, biocompatible, and piezoelectric substrate is presented. The printed tank (resonant frequency of ≈1...

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...
