Circuit or electronic components are useful elements allowing the realization of different circuit functionalities. The resistor, capacitor and inductor represent three commonly known basic passive owing to their fundamental nature relating them four variables, namely voltage, magnetic flux, current electric charge. memory resistor (or memristor) was claimed be fourth element, complementing ind...

Passive filters are often used for electromagnetic interference (EMI) suppression of high voltage (HV) DC power supplies electric vehicle (EV) motor controllers. The current the bus saturates differential mode (DM) magnetic ring, while leakage inductance common (CM) inductor as DM is usually very small, resulting in almost no EMI. A design method broadband high-current air-core passive filter p...

This paper presents a novel wide tuning range CMOS Voltage Controlled Oscillator (VCO). VCO uses an on-chip variable inductor as an additional variable element to extend the tuning range of VCO. The fabricated variable inductor achieves the variable range of 35%. The VCO was fabricated using 0.35 μm standard CMOS process, and can be tuned continuously from 2.13 GHz to 3.28 GHz (tuning range of ...

A 2.5D EM-simulator has been used to study how planar inductor performance is influenced by an epitaxial substrate. The simulation model used has been adjusted and verified by measurements on an octagonal inductor fabricated in a submicron CMOS technology. The impact of the epitaxial layer has been studied by sweeping it’s permittivity, thickness, and resistivity. The results show that typical ...

On-chip circular vertical solenoid inductors have been designed and fabricated using standard 6-metal layer CMOS process. Compared to the 4.1nH circular planar spiral inductor on the same chip, the 4.8nH solenoid inductor gives about 20% increase in maximum quality-factor (QF) and 50% increase in self-resonant frequency (SRF), but only occupies 20% of the area. The inductor impedance can be mod...

A new structure of the solenoid inductor is presented in this paper. The proposed solenoid inductor has been simulated in a standard 0.18um one-poly-six-metal (1P6M) CMOS process. The proposed inductor products higher quality factor and inductance value in compare with the traditional designs. Furthermore, the new structure shows more improvement in the peak of quality factor so the number of t...

This paper presents a high-efficiency inductorless self-controlled rectifier for piezoelectric energy harvesting. High efficiency is achieved by discharging the piezoelectric device (PD) capacitance each time the current produced by the PD changes polarity. This is achieved automatically without the use of delay lines, thereby making the proposed circuit compatible with any type of PD. In addit...
