New CMOS Realization of Z Copy Voltage Differencing Buffered Amplifier and Its Current-Mode Filter Application

Abstract

In this paper, a new CMOS realization of Z Copy Voltage Differencing Buffered Amplifier (ZC-VDBA) is presented. The performance of the proposed circuit is demonstrated on a new current-mode Kerwin-Huelsman-Newcomb (KHN) filter application, employing two ZC-VDBAs and two grounded capacitors. The circuit simulations are verified using BSI M3 0.18 mu m level-7 SPICE parameters.
