Abstract
AbstractWith the increasingly sophisticated functionality of integrated circuits, dynamically reconfigurable circuits in which the structure of the circuit can be dynamically changed using single circuit units have attracted much attention. The neuron MOS transistor, a flexible device that functions in a manner that resembles the working of a biological neuron, has been developed as a high‐functionality device for use in such circuits. In this paper we propose a multiple‐input neuron MOS variable logic circuit that implements symmetric functions. The proposed design method makes use of a pre‐inverter and a main inverter; here we propose to allow the pre‐inverter to be controlled by a symmetric function. In this way the design allows well‐balanced capacity segmentation and can be easily extended to multiple inputs. In addition, it is possible to reduce the number of elements in the circuit compared with existing methods. We have created a prototype of the proposed circuit using the ON Semiconductor 1.2−µm CMOS standardized process and its functionality was verified in simulations and experiments using HSPICE. © 2006 Wiley Periodicals, Inc.
