Single-electron pass-transistor logic with multiple tunnel junctions and its hybrid circuit with MOSFETs

To improve the operation error caused by the thermal fluctuation of electrons, we propose a novel single-electron pass-transistor logic circuit employing a multiple-tunnel junction (MTJ) scheme and modulate a parameters of an MTJ single-electron tunneling device (SETD) such as the number of tunnel junctions, tunnel resistance, and voltage gain. The operation of a 3-MTJ inverter circuit is simulated at 15 K with parameters C-g=CT=Cclk=1 aF R(T=)5 MOmega, V-clk=40 mV and V-in =20 m V Using the SETD/MOSFET hybrid circuit, the charge state output of the proposed MTJ-SETD logic is successfully translated to the voltage state logic.
