Abstract :
In this paper, high frequency CCII based oscillators and multifunction filters are presented. A system level investigation of these configurations characteristics and CCII nonidealities effects are done. The authors emphasize the fact that the proposed applications are well suited for integration since their characteristics can be tuned by simple action on their bias current. Implementations of these topologies based on an improved high frequency translinear CCII were done. The oscillator has a variable oscillation frequency tunable in the range [333 MHz-867MHz] by varying a dc current between 50muA and 400muA. Moreover, two based current mode and voltage mode multifunction filters were implemented. The current mode filter has a tunable natural frequency in the range [512MHz-1GHz] and the voltage mode filter is also implemented having a natural frequency equal to 100MHz
