Abstract

In this work, new tunable basic building blocks employing inverting second-generation current conveyors (ICCIIs) are presented for analogue signal processing. Using two different approaches, ICCII-based tunable active circuit design can be performed. The first approach is the use of MOSFETs operating in the triode region, which are connected between the Y and X terminals of the inverting conveyors. In this case, thanks to the inverting property of ICCIIs, the triode MOSFETs operate very linearly since they receive a balanced differential voltage between their drain and source terminals. In the second approach, the conveyor is modified to a current controlled one (ICCCII), for which, the intrinsic series parasitic resistance of the X terminal (RX) is adjustable via a biasing current.
