In this paper, a novel lossless floating inductor simulator with four resistors, a grounded capacitor and five two-terminal active components such as negative impedance converter, current follower and voltage follower, is presented. The capacitor in the floating inductor simulator is grounded, which provides suitability for integrated circuit fabrication. However, it needs resistive matching co...

An average model of SEPIC converters with coupled or uncoupled inductors was developed and verified against cycle-by-cycle s i m u l a t i o n s . The model can be used as-is by any modern circuit simulator to run steady state (DC), large signal (transient) and small signal (AC) analyses. The leakage inductances were taken into account and treated separately from the mutual inductance. The prim...

In this article, a hybrid wireless power transfer system, which combines induction heating (IH) and inductive functionalities, is proposed to improve the performance of domestic IH application with small loads weakly coupled distant inductors. Considering basic single-inductor application, system adds secondary inductor series compensation capacitor directly attached ferromagnetic cookware. The...

An eddy current sensor with an ink-jet printed flexible inductor has been designed and fabricated. The inductor has been designed by means of software developed in-house. It has been fabricated by ink-jet printing with silver ink on a flexible substrate. The inductor is a part of the oscillator circuit whose oscillating frequency is measured by a microcontroller. The sensor characteristics have...

Inductor with gradual changed metal width and space by good design can get better Q factor than the inductor with fixed metal width and space. In this paper, a simple wide-band inductor model is presented considering both the increase of resistance and the decrease of inductance due to the skin and proximity effects. This model has been verified with simulation and the experimental results of s...

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED element and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and uses an external inductor. The inductor is embedded in the substrate of the backplane and has a spiral geometry. The DC-DC converter is highly efficient, but a f...

A active inductor in CMOS techonology with a supply voltage of 1.8V is presented. The value of the inductance L can be in the range from 0.12nH to 0.25nH in high frequency(HF). The proposed active inductor is designed in TSMC 0.18-um CMOS technology. The power dissipation of this inductor can retain constant at all operating frequency bands and consume around 20mW from 1.8V power supply. Induct...

This paper demonstrates an on-chip di/dt detector circuit. The di/dt detector circuit consists of a power supply line, an underlying spiral inductor and an amplifier. The mutual inductor induces a di/dt proportional voltage, and the amplifier amplifies and outputs the value. The measurement results show that the di/dt detector output and the voltage difference between a resistor have good agree...

The inductors made of carbon Nanotube (CNT) have been proposed. Though the fabrication of the proposed inductor is still challenging and has many problems, merits of the proposed inductor are following, (i)The magnetic field induced by the current in CNT is about one thousand times larger than that induced by the current in normal copper wire. (ii)The large magnetic field results in the large i...

This paper presents an area-effective bandwidth enhancement technique using interwoven inductors. Inductive peaking is a common practice for bandwidth enhancement, however the area overhead of inductors is a serious issue. We implement six or four inductors into an interwoven inductor. Furthermore parasitics of the inductors can be reduced. The proposed inductor is applied to a laser-diode driv...
