Computing with carbon nanotubes: Optimization of threshold logic gates using disordered nanotube/polymer composites

Chemical logic Gates with adaptive Computing

We present a method that is capable of implementing information transfer without any rigidly controlled architecture using the light-sensitive Belousov-Zhabotinsky (BZ) reaction system. Chemical wave fragments are injected into a subexcitable area and their collisions result in annihilation, fusion or quasi-elastic interactions depending on their initial positions. The fragments of excitation b...

Design of Near-Threshold CMOS Logic Gates

Numerous efforts have made to balance the tradeoff between power consumption, area and speed of a design. While studying the design at the two extreme ends of the design spectrum, namely the ultra-low power with acceptable performance at one end and high performance with power within limit at the other has not made. One solution to achieve the ultra-low power consumption is to operate the desig...

Differential Implementations of Threshold Logic Gates

2. CAPACITIVE SOLUTIONS This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (switched capacitor and floating gate), and conductance/current. The concept underlying capacitive TLGs is the use of an array of capacitors to implement the weighted sum of inputs. The idea was introduced as early as 1966 [6]. Capacitive TLGs can be c...

Deriving Weights for Single Threshold Logic Gates Using Decomposition

This paper revisits the problem of deriving weights for single threshold logic gates. The conventional method of look-up tables of Chow’s parameters is only available for functions with up to 8 variables. Above this no systematic method is known. This paper proposes a method of decomposition to reduce the problem to a number of lower dimensional problems. Weights are then derived by recombining...
