Design of a Ternary Logical Circuit Using the Au-DNA-Ag Memristor

An asymmetrical element based on Au-DNA-Ag has been proposed and designed to play the role of a DNA memristor. The role of the DNA length here is to decrease the power and size of the memristor. In fact, according to the context and simulation results, the combination of metal-DNA-metal can play the role of a memristor and produce a similar behavior as a memristor. It has been shown that the asymmetrical design, i.e., two different metals, causes a sharp decrease in flow and thus power consumption. With this element, a ternary logic has been designed and simulated with much less power in comparison with similar circuits. With the help of this device, a new, efficient and ternary reversible logic gate has been proposed and designed. With the help of this proposed gate, all logic circuits with minimum quantum cost, garbage output, power consumption and delay were proposed and designed. In fact, in this research, a reversible logic was proposed that has much less quantum cost, garbage output, power consumption and delay than previous designs.
