An optimized low voltage and High Frequency CCII based multifunction Filters

In this paper, a low voltage current conveyor (CCII) based multifunction filter is presented. Firstly, thanks to an optimizing heuristic, an optimal sizing of a low voltage low power CMOS current conveyor (CCII) was done. Hence, we improve static and dynamic performances of this configuration. The optimized CCII configuration has a current bandwidth of 1.103GHz and a voltage bandwidth of 1.18GHz and 33.4 Ω as RX parasitic resistance value. Secondly, implementation of a multifunction filter based on this configuration was done. The current mode Alter has a tunable central frequency in the range [50MHz-800MHz]. PSPICE simulations are presented to demonstrate these results.
