Abstract

In this paper, based on a novel synthesis, a set of new simplified circuit design to implement the linguistic-hedge operations for adjusting the fuzzy membership function set is presented. The circuits work in current-mode and employ floating-gate MOS (FG-MOS) transistors that operate in weak inversion region. Compared to the other proposed circuits, these circuits feature severe reduction of the elements number, low supply voltage (0.7 V), low power consumption (<200 nW), immunity from body effect and wide input dynamic range (>60 dB). Simulation results by Hspice confirm the validity of the proposed design technique and show high performance of the circuits.
