A new linearization technique using a CCII doublet transconductor in CMOS technology

In this paper, a new linearization technique using a second generation of current conveyor doublet (CCIID) in CMOS technology is presented. The proposed CCIID is made up a mixed parallel and cross connection of two CCII stages. The output current is given by the difference between the two output currents provided by the two CCII stages. Due to the cross-connection of the two CCII stages, the nonlinearities of these currents are canceled, which determines a linear output current in a large dynamic range.
