Abstract :
A new design of a positive-type second-generation current conveyor (CCII+) based on quasi-floating gate MOSFETs (QFGMOS) is introduced. The proposed CCII+ is compared with others showing bandwidth advantages, e.g. it reaches 257MHz and 523MHz for the voltage tracking (between ports Y to X) and current tracking (between ports X to Z), respectively, while the parasitic resistance at port X is low as Rx=5.1794Ω. This new CCII+ is used to implement Chua´s diode that is modeled by a piecewise-linear (PWL) function consisting of two negative slopes and two break points. That way, Chua´s chaotic oscillator is designed using standard CMOS technology of 0.5Ω. SPICE simulation results are provided to show the suitability of the proposed CCII+ based on QFGMOS for generating chaotic phenomena through implementing Chua´s circuit.
