The optimized structure is then applied in the design of a high frequency multifunction tunable filter and a chaos generator. Firstly, heuristic algorithm is used for optimal sizing regarding static and dynamic performances. An optimal sizing of a low voltage low power CMOS Current Conveyor (CCII) was then done. The optimized CCII configuration has a current bandwidth of 1.53 GHz and a voltage bandwidth of 1.406 GHz and 190 Ω as Rx parasitic resistance value. Secondly, implementation of an ameliorated multifunction filter based on this configuration was presented and a new RLC low voltage chaos generator using the second-generation current conveyor (CCII) as active building block is presented. The current mode filter has a tunable central frequency in the range [480-638 MHz]. PSPICE simulations are presented to demonstrate these results.]]>Sedra, A. and K. Smith,197017132134Fabre, A., O.
