the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

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 ...

Recently, interest in fractional-order inductors (FOIs) has increased since they allow for accurate and robust models of dynamical systems to be designed. However, practical implementation these not been possible due the lack single FOI realizations. To address this challenge, work, we propose a simple-to-realize inductor design with variable constant phase angle (CPA). The relies on characteri...

When the input inductor operates in discontinuous current mode (DCM), Cuk converter can automatically achieve power factor correction (PFC) function with only a simple voltage control loop. However, conventional PFC suffers from high intermediate capacitor because of lack feedback and relatively low (PF). In this paper, using variable which varies transient rectified is proposed to enhance PF r...
