Power analysis dataset for QCA based multiplexer circuits

Abstract

Power consumption in irreversible QCA logic circuits is a vital and a major issue; however in the practical cases, this focus is mostly omitted.The complete power depletion dataset of different QCA multiplexers have been worked out in this paper. At −271.15 °C temperature, the depletion is evaluated under three separate tunneling energy levels. All the circuits are designed with QCADesigner, a broadly used simulation engine and QCAPro tool has been applied for estimating the power dissipation.

2.1. Analysis of power dissipation

For estimating the power dissipation of reported multiplexers [1], [2], [3], [4], [5], [6], [7], [8], [9], [10] QCAPro; a power analyzing tools for QCA design has been applied. This tool estimate polarization error and non-adiabatic switching power loss in Quantum-dot Cellular Automata (QCA) circuits. It uses a fast approximation based technique to estimate highly erroneous cells in QCA circuit design. In our study, power estimation of all the multiplexers has been achieved at a stable temperature T= −271.15 °C. The power dissipation by a QCA cell is calculated using the Hartree–Fock mean-field approach approximation which is illustrated as [11], [12], [13], [14], [15]

$$H=\left[\begin{array}{cc}{\displaystyle \frac{{-E}_k}{2}}{\sum }_i{C}_i{f}_{i,j}& -\gamma \\ -\gamma & {\displaystyle \frac{E_k}{2}}{\sum }_i{C}_i{f}_{i,j}\end{array}\right]=\left[\begin{array}{cc}{\displaystyle \frac{{-E}_k}{2}}\left(C_{j-1}+C_{j+1}\right)& -\gamma \\ -\gamma & {\displaystyle \frac{E_k}{2}}\left(C_{j-1}+C_{j+1}\right)\end{array}\right]$$ (1)

According to the upper bound power dissipation model [14] the power dissipation by a QCA cell is given as

$$P_{\mathit{diss}}=\frac{E_{\mathit{diss}}}{T_{\mathit{cc}}}\langle \frac{\mathrm{ħ}}{{2T}_{\mathit{cc}}}{\overrightarrow{\mathrm{Г}}}_{+}\times \left[-\frac{{\overrightarrow{\mathrm{Г}}}_{+}}{|{\overrightarrow{\mathrm{Г}}}_{+}|}\tan h\left(\frac{\mathrm{ħ}|{\overrightarrow{\mathrm{Г}}}_{+}|}{k_{B}T}\right)+\frac{{\overrightarrow{\mathrm{Г}}}_{-}}{|{\overrightarrow{\mathrm{Г}}}_{-}|}\tan h\left(\frac{\mathrm{ħ}|{\overrightarrow{\mathrm{Г}}}_{-}|}{k_{B}T}\right)\right]\rangle$$ (2)
