Abstract:

 

The Z copy current differencing transconductance   amplifier (ZC-CDTA) is a new current-mode active element that was introduced   recently. ZC-CDTA is improved from the current differencing transconductance   amplifier (CDTA) and has increased its universality. In the current study, a   CMOS implementation of ZC-CDTA is proposed. The first stage of ZC-CDTA   consists of a current differencing unit. The output stage consists of a dual   output transconductance amplifier. Furthermore, a third-generation current   conveyor is used to copy the Z terminal current instead of a classical   current mirror. A fourth-order filter application employing ZC-CDTAs is   given and simulation results are added. The ZC-CDTA-based filter is designed   starting from a previous filter structure that employed conventional CDTAs.   Thanks to the Z copy, the high-pass filter output problem is solved for the   conventional CDTA filter structure. AMS 0.18-μμ\mu m CMOS parameters are   used for the simulations.
