LOW VOLTAGE CCII TECHNIQUES COMPOSITE TRANSISTOR AND BULK DRIVEN

To proof low voltage techniques are valid in current conveyor design, Bulk driven and composite transistor (self cascode) techniques are used to get high performance results from CCII in low voltage supply. Conventional operational amplifier circuit from literature was our choice as core of the design. Our Focus with using low voltage techniques is study the frequency characteristics of a CCII based miller compensated operational amplifier. Orcade 9.2 and 0.7 m CMOS process model from AMIS used for simulation. The current-mode approach is voltage mode alternative to obtain high performance architectures, the most advantages of current mode is higher gain bandwidth product. In this work design and construct low voltage second generation current conveyor, their performance are discussed here with corresponding to current frequency response, input and output impedances, dynamic range, finally a comparison with the conventional techniques has been presented.
