We show how to build an inductorless version of the classic Chua’s circuit. The goal is to build Chua’s circuit quickly and easily. To this end, only off-the-shelf components are used. A suitable inductor for Chua’s circuit is often hard to procure. Here, the inductor is replaced by a single op-amp synthetic inductor circuit. The synthetic inductor is novel in the sense that it is not a gyrator...

A differentially excited symmetric inductor that enhances inductor quality ( ) factor on silicon RF ICs is presented. Compared with an equivalent single-ended configuration, experimental data demonstrate that the differential inductor offers a 50% greater factor and a broader range of operating frequencies. Predictions from full-wave simulations and a physics-based SPICE-compatible model are va...

The generalised steady-state analysis of the multi-phase interleaved boost converter with coupled inductors operated in continuous inductor current mode is addressed. The analytical expressions for efficiency, inductor and input currents, and output voltage are derived from the transformed average state–space model. Generalised expressions for the input and inductor current ripples and the outp...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper presents a high-Q MWCNT (Multi Wall Carbon Nano-Tube) network based pulse-shaped on-chip embedded nano-inductor for power electronic circuits. This high-Q inductor is fabricated using a composite of MWCNT (multi Wall Carbon Nano Tube) network and Fe in semiconductor processing environment. A layer of nano composite film (Cu/CoFe2o4) is pat...

In current trend for portable wireless communication applications, we require high Q on-chip inductors. In this paper an on-chip 3-D spiral inductor is proposed. High quality factor is achieved by reducing oxide capacitance between substrate and conductor considering permittivity of a substrate. Losses in the structure are reduced by considering high conductivity material like copper or gold. I...

In this study investigation is done on an H-bridge switched inductor base cascade multilevel DC-DC boost converter. The proposed multilevel DC-DC boost converter topology improves the conversion efficiency of traditional topology. The proposed boost converter topology is differing from the traditional topology by the addition of switched inductor circuit. The switched inductor improved the conv...

This paper describes the Q enhancement of inductor or resonance circuit based on the controlled CMOS transonductance, which is applicable to either on-chip inductor or off-chip inductor. The proposed circuit configuration of high Q enhancement is evaluated for the RF transmit filter of a LTE mobile comm’s micro base station, with the Q factor of over 3000 and the capacity of 10W. A tunable filt...

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...
