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...

The present trend of aerospace industries is being shifted towards a “More Electric Aircraft” system which needs to be high power dense. For this purpose, the integration technologies have gained massive interest, providing benefits reduced losses, weight, volume and cost. In article, concept passive filter inductor presented for permanent magnet synchronous motor. integrated motor eliminates n...

Two essential technologies for a 3D Solid State Drive (3DSSD) with a boost converter are presented in this paper. The first topic is the spiral inductor design which determines the performance of the boost converter, and the second is the effect of TSV’s on the boost converter. These techniques are very important in achieving a 3D-SSD with a boost converter. In the design of the inductor, the o...

Because the on-board charger (OBC) is installed in electric vehicles (EVs), high power density is regarded as a key technology. Among components of the OBC, inductors occupy more than 30% of the total volume. Thus, it is important to reduce the volume and the weight of inductors while maintaining thermal stability. Discontinuous conduction mode (DCM) can satisfy these requirements; however, onl...

As operation frequencies and performance requirements of wireless devices increase, the resultant demands on the performance of passive components also increase. Miniaturization of inductive components for high frequency has been a key research area to address this issue; however, in general, miniaturized integrated inductors can suffer from low Q factors and/or self-resonant frequencies when c...
