This article presents a new circuit topology for high voltage gain active switched boost quasi Z-source inverter (qZSI) and pulsewidth modulation (PWM) technique. The higher boosting capability with lower number of elements, the continuous source current, less stress across devices, having common ground are main advantages proposed structure. is twice that conventional capacitor-assisted qZSI (...

|A voltage controlled di erential injection locked frequency divider (VCDILFD) with a large locking range is designed in a 0:24 m CMOS technology. A 29% locking range is achieved by an optimal inductor design and also by employing high Q accumulation mode MOS varactors to change the free{running oscillation frequency of the divider. The measurement results show frequency division at 5GHz with m...

frequency to retain the triangular shape of the inductor current. It will be assumed in the following, therefore, that.the output signal of amplifier A, includes a remnant of the inductor current triangular waveform (except for possible curvature of the corners) multiplied by a constant (kJ. In CM realisation (Fig. 2), the output of the error amplifier V;, modified by a 'compensation slope' Mc ...

A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented. By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant. Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple. So the volume of Z-source network inductor can be designed smaller...

This paper presents a new circuit topology designed to minimise the weight of the control circuit required to actuate multiple piezoelectric actuators. It can independently set the phase and bias voltage on each piezoelectric actuator through the use of a single inductor. This is highly desirable in weight constrained applications such as unmanned aerial vehicles as the ferroelectric material r...

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 an LC-VCO 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 are beneath the inductor...

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...

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...

High-speed digitizers operating at sampling rates higher than 10GS/s require low-pass anti-aliasing filters in the multi-GHz range. Asynchronous Time-Interleaved (ATI) also need before digitization, and additional requirements on their design are set by this specific application. In integrated solutions, inductor-less important for minimizing chip area footprint. paper, we present of a 6th...
