Novel low-power accurate wide-band CMOS negative-second-generation-current-conveyor realizations based on Floating-Current-Source building blocks

This paper presents two novel Floating Current Source (FCS) based CMOS negative second generation current conveyor (CCII-) realizations suitable for very large scale implementation. The proposed realizations provide high voltage and current tracking accuracy, as well as large voltage and current transfer bandwidths. Simulations show that the first proposed wide band CCII- bandwidth is about 972 MHz. Targeting low power dissipation, a second low power version of the wide band CCII- is proposed at the expense of lower bandwidth. In addition, a fair comparison is held between the proposed realizations and the only FCS-based CCII- realizations in the literature to show the strength of the proposed circuits.
