The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...

A high Q-factor (quality-factor) spiral inductor fabricated by the CMOS (complementary metal oxide semiconductor) process and a post-process was investigated. The spiral inductor is manufactured on a silicon substrate. A post-process is used to remove the underlying silicon substrate in order to reduce the substrate loss and to enhance the Q-factor of the inductor. The post-process adopts RIE (...

The modern Power Electronic Systems generally require high quality, portable, light weight, reliable and efficient power supplies. The switched mode power supplies (SMPS) technology is developing very rapidly. This bidirectional dc-dc converter has attractive features because of its high efficiency and compact size and is used in various industrial applications. The switching action of converte...

Usually basic dc-dc boost converters are unable to provide high step up voltage gain due to the effect of power switches, rectifier diodes and equivalent series resistance of inductors and capacitors and the voltage stresses on the power switches are high. This paper proposes a simple transformerless dc-dc converters to achieve high step up voltage gain without an extremely high duty ratio. The...

Power electronic converter systems for applications such as telecom, automotive, and space can have dc voltage buses that are backed up with batteries or super-capacitors. These batteries or super-capacitors are connected to the buses with bidirectional dc–dc converters which allow them to discharged or charged, depending on the operating conditions. Bidirectional dc–dc converters may be isolat...

Owing to the low voltage level that renewable energy sources like solar panels frequently provide, and limited capability of simple boost converter, need for high gain step-up dc-to-dc converters are increased. In this article a single switch topology with efficiency is developed. To obtain gain, described employs three windings coupled inductor multiplier cell method. get innovative converter ...

This article presents a commutated-inductor–capacitor (commutated- $LC$ ) or switched- circuit that acts as radio frequency (RF) delay line. Thanks to its linear-periodically time-varying (LPTV) operation and fully passive implementat...

This paper presents a 40-MHz hybrid CMOS/GaN integrated multiphase dc–dc switched-inductor buck converter with a maximum 20-V input voltage. The half-bridge switches are realized using lateral AlGaN/GaN HEMTs, while the drivers and other circuitry are implemented in standard 180-nm CMOS. The interface between the CMOS and GaN dice is achieved through face-to-face bonding, reducing inductive par...

A striped inductor and its utilization of a voltagecontrolled oscillator (VCO) are studied with the aim of suppressing phase noise degradation in Kand Ka-bands. The proposed striped inductor exhibits reduced series resistance in the high frequency region by increasing the cross-sectional peripheral length, as with the Litz wire, and the VCO of the striped inductor simultaneously exhibits a lowe...
