High-Performance Second-Generation Current Conveyor and Its Applications

In this paper, a MOSFET-only voltage divider based second-generation current conveyor (MOCCII +) is proposed. The input stage of the proposed MOCCII + is based on the translinear loop and the output stage is biased by the reference voltage that is derived from the power supply with the help of a MOSFET-only voltage divider. The voltage divider biasing circuit is used to increase the current linearity range. The proposed MOCCII + has high voltage transfer bandwidth, wide input current linearity range, and high current gain. The applications of proposed MOCCII + such as current integrator and current differentiator are also presented to show the worthiness of the proposed MOCCII + . The proposed circuits have been simulated using UMC 0.18 µm CMOS technology with the supply voltages of ± 0.9 V.
