In this area traditional voltage-mode techniques are going to be substituted by the current-mode approach which has the advantage to overcome the gain-bandwidth product limitation typical of operational amplifier. Then they do not require high voltage gains and have good performance in terms of speed bandwidth and accuracy. Inside the current-mode architectures the current-conveyor (CCII) can be considered the basic circuit block because all the active devices can be made of a suitable connection of one or two CCIIs. Recent advances in integrated circuit technology have also highlighted the usefulness of CCII solutions in a large number of signal processing applications. This project describes different topologies of CCIIs. All topologies have been simulated in different CMOS process technologies using Eldo Spice tool and layout is made using Mentor Graphics Back End tools like IC Station and DA-IC. Different characteristics such as gain, bandwidth, terminal impedances, slew rate, dynamic range, input-output current characteristic and offset are measured and tabulated for all the CCII topologies. | | Keywords : | | - gain,bandwidth,terminal impedances, slew rare, dynamic range, current mode techniques, voltage mode techniques.,
