In this paper, parametric analysis of miniature on-chip 3-D inductor is presented. The effect of conductor width, spacing between conductors and number of turns of inductor on Quality factor (Q-factor), inductance and Self-resonant frequency (SRF) are studied. Improvement in percentage increase of Q-factor is due to increase in conductor width. It can be found that ~72% of on-chip area reductio...

Extensive experimental results and detailed investigations of the performance of on-chip circular double-spiral stacked inductors on silicon substrates are presented. Based on a proposed equivalent circuit model and measured S-parameters using the de-embedding technique, the inductance L, resonant frequency fres, Q-factor, coupling capacitance between the upper and lower spirals, and oxide capa...

We consider the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter ε > 0. An explicit form of the singular part of the corresponding potential u is given. This allows to construct the limit potential u (as ε → 0) and an approximation of the inductance coefficient L. We establish some estimates of the deviation u − u and of the error of approximation...

Perhaps the simplest Colpitts oscillator to construct and get running. Because there is no load on the inductor a high "Q" circuit results with a high L/C. Colpitts Oscillator Tutorial and the theory behind the design of the Colpitts Oscillator which uses a LC Oscillator tank circuit to generate sine waves. The Colpitts Oscillator Circuit Characterised By Tapping The Midpoint Of The Capacitive ...

A new integrated magnetic full wave dc/dc converter1 that provides flexible transformer design by incorporating an independent output inductor winding is introduced. The transformer is implemented on a traditional three-leg magnetic core. The inductor winding can be separately designed to control the output current ripple. The cross-sectional area of the inductor core leg can be reduced dramati...

In this paper, an integrated passive device (IPD) inductor modeling is demonstrated. The IPD technology is a system in package (SiP) solution where passive devices with high quality can be fabricated on a chip and then connect with another circuit chip by using flip-chip micro-bump bonding. For an RF circuit simulation, the IPD inductor model is built and verified from the measurement results. ...

This paper investigates a current mode active inductor. In the proposed active inductor, three current mirrors have been connected to each other to realize the negative feedback. This active conductor has a two layer transistor structure. A 4.257 GHz, 1.2-V power supply non-inductive LC negative resistor oscillator, base on two of the proposed active inductors, is demonstrated. Keywords-active ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1V voltages are everywhere now. Meanwhile, intermediate bus voltages have stayed the same or increased depending on the application. To make things more challenging for power supply designers, system frequency requirements have steadily increased to support smaller induc...

The inductor is a substance that is found in the embryo. It fu..11ctions to evoke cellular proliferation and cellular differentiation. The inductor is more active in some areas of the embryo than in other areas. These active induction areas may be called induction fields. The inductor vvas dis covered in the embryo. Spemann, Vo gt , and Na.ngold made significant contributions to the field of ex...
