This paper presents a proposal and an experimental analysis of behavioral emulator of so-called z-copy controlled-gain voltage differencing current conveyor (ZC-CG-VDCC) based on commercially available devices. Most of them are electronically (by DC voltage) controllable. This work represents a suitable example of preliminary stage of development of an active device before its fabrication on silicon. This approach of development provides certain and significant information about basic functionality of the active device or the whole application and proves expected theory. The particular results of tested ZC-CG-VDCC implementation in frequency domain (transfers, gains, impedances) and DC domain (dynamics, linearity) are shown.
