A Second Generation Current Controlled Current Conveyor Realization Using Cascode Current Mirror : A CCCII Realization Using Cascode Current Mirror

Abstract

A new CMOS second generation current controlled current conveyor (CCCII) structure is reported in this paper. The proposed circuit adopts cascode current mirrors, which X-terminal and Y-terminal are used MOS composite tube in series structure with good following characteristics, large linear range, low power consumption and port parasitic resistance control characteristics. Finally, the circuit is simulated by Pspice using 0.18 μm process. The linear input ranges of X-terminal and Y-terminal are −2 ~ 2 mA and −2 ~ 2 V, respectively. The offset current of Z-terminal is 0.65 μA, and the power consumption of the circuit is only 0.415 μW at 2 V supply voltage.
