Abstract
Carbon Nano-Tube Field Effect Transistors (CNTFETs) are being widely studied as possible successors to silicon MOSFETs. Using current mode has many advantages such as performing sum operation by means of a simple wired connection. Also, direction of the current can be used to exhibit the sign of digits. It is expected that the advantages of current mode approaches will become even more important with increased speed requirements and decreased supply voltage. In this paper, we present five new circuit designs for differential absolute value in current mode logic which have been simulated by CNTFET model. The considered base current for this model is 2 µA and supply voltage is 0.9 V. In all of our designs we used N-type CNTFET current mirrors which operate as truncated difference circuits. The operation of Differential Absolute Value circuit calculates the difference between two input currents and our circuit designs are operate in 8 logic levels.
