Single electron devices have ultra-low power consumption and high integration density which makes them promising candidates as basic circuit elements of the next generation ultra-dense VLSI and ULSI circuits. In this paper, design, simulation and analysis of 2-to-4 decoder using single-electron tunnelling technology based threshold logic gate is presented. The circuit consists of four buffered threshold logic gates. The logic operation of the circuit is simulated and verified using Monte Carlo simulation. The free energy history and stability diagram verified the correct functioning of the circuit
