An inductorless CMOS realization of Chua s circuit
نویسندگان
چکیده
In this paper, an inductorless CMOS realization of Chua s circuit [IEEE Trans. Circ. Syst.––I 1985;32:798] is presented. The circuit is derived from the dimensionless form of Chua s circuit and can generate Rossler or double-scroll attractors by changing a single capacitor s value. Variables are represented in the current domain to facilitate adding or subtracting variables. New Gm–C representation of the Chua diode as well as the Chua circuit are presented. The circuit can operate from supply voltage as low as 1.5 V. Transistor-level simulation results using PSpice in 0.5 lm Mietec process are presented. 2003 Published by Elsevier Science Ltd.

Improved Realization of Mixed-Mode Chaotic Circuit
An improved realization of mixed-mode chaotic circuit which has both autonomous and nonautonomous chaotic dynamics is proposed. Central to this study is inductorless realization of mixed-mode chaotic circuit using FTFN-based inductance simulator. FTFN-based topology used in this realization enables the simulation of ideal floating and grounded inductance. This modification provides an alternati...
متن کاملOptimized Standard Cell Generation for Static CMOS Technology
Fabrication of an integrated circuit with smaller area, besides reducing the cost of manufacturing, usually causes a reduction in the power dissipation and propagation delay. Using the static CMOS technology to fabricate a circuit that realizes a specific logic function and occupies a minimum space, it must be implemented with continuous diffusion runs. Therefore, at the design stage, an Euleri...

متن کامل1–10GHz Inductorless Receiver in 0.13μm CMOS
In this paper, we describe an inductorless wideband radio receiver architecture from 1GHz to 10GHz. Two receiver RF frontends designs are presented and compared: a traditional inductor peaking LNA and mixer (IPLM) and a capacitive peaking LNA and mixer circuit (CPLM). Measurement results indicate that CPLM with the same bandwidth has better linearity, comparable noise figure and uses only 17% m...
متن کاملGeneric RC realizations of Chua's Circuit
Since its discovery, Chua’s circuit has served as the main prototype circuit for studying chaos in electronic systems [Matsumoto, 1984]. Several realizations of this circuit have been introduced in the literature [Cruz & Chua, 1992; Kennedy, 1992, 1995; Rodriguez-Vazquez & Delgado-Restituto, 1993; Zhong, 1994; Morgul, 1995; Elwakil & Kennedy, 1999a, 1999b, 2000]. These various implementations w...
