Abstract: In many power factor correction applications, the power level can reach maximum value and sometimes the input voltage also will be too high. For high power and high voltage applications the inductor volume and weight is the major concern of the conventional boost converter. In this paper the two inductor boost converter is adopted which uses smaller inductors yielding high power densi...

We propose a universal MEMS technology platform for fabricating integrable passive components for radio frequency (RF) integrated circuits. This platform is based on a novel surface-micromachined MicroElevator by Self-Assembly (MESA) techque. Both high-Q inductors and variable capacitors can be realized by the MESA technology. A surface-micromachined spiral inductor that is raised by 250 pm abo...

DC DC converters are widely used in a variety of applications. It is mostly used in tracking maximum power point of PV array. The tapped inductor is a feasible method to extend the voltage conversion ratio. In this paper, the effect of tapped inductor in a boost converter is discussed. This paper provides a detailed design and analysis of a tapped inductor boost converter. The performance of th...

The generation of sine wave at low frequency is very tedious because the size of the inductors used in the circuit is very large and bulky. Hence the inductor is replaced with the simulated inductor. This study deals with the generation of sine wave from an active tuned oscillator which consists of the simulated inductor and capacitor. The oscillator makes use of the basic blocks of a band pass...

This paper presents a novel predictive digital control method for boundary conduction mode PFC converters without the need for detecting the inductor current. In the proposed method, the inductor current is predicted by analytical equations instead of being detected by a sensing-resistor. The predicted zero-crossing point of the inductor current is determined by the values of the input voltage,...

This paper presents the design of square spiral inductor on FR4 substrate for different number of turns. Various simulations based on the incipient models were done by varying geometric parameters. Here, we vary the number of turns from 5 to 9 and find out their effect on Inductance (L), Quality factor (Q) and Self resonant frequency (SRF). The development of inductors for RF telemetry applicat...

Several realizations of Chua’s circuit have been proposed in the literature. The methodologies used in these realizations can be divided into two basic categories. In the first approach, a variety of circuit topologies have been considered for realizing the nonlinear resistor, NR in Chua’s circuit. The main idea in the second approach related to the implementation of the circuit is an inductorl...

This paper presents a prototype of wireless sensor node for power management of information and communication technology (ICT) devices at low AC frequency. Electromagnetic simulation and experiments were carried out for discussing the miniaturization of the sensor node. The good fit between the simulation and experimental results on the induction voltage of a commercial meso-scale inductor, sug...

This paper proposes an ultra compact LC-VCO. Due to the speed-up of CMOS digital circuits, jitter of ring oscillators is becoming a critical problem. Even though a LCVCO has a better phase noise, a layout size of on-chip inductor is a problem as a clock generator. Thus, the proposed LC-VCO consists of a very compact stacked-spiral inductor and active components placed beneath the inductor. The ...

The paper presents a unified steady-state analysis of PWM SEPIC converter with coupled inductors and separate inductors for both continuous and discontinuous conduction modes. The results of this simplified analysis allow to determine the operating point of converters and further the small-signal low-frequency parameters of linear model, and to design the converter too. The expressions of all s...
