Single-electron device based on the majority logic.

在这个项目中，我们开发了基于多数逻辑原理的单电子门电路。多数逻辑门电路由电容阵列和单电子反相器组成，电容阵列用于输入求和，单电子反相器用于阈值操作。它接受奇数个输入，并根据多数决定原则产生相应的输出;如果大多数输入为1，则产生逻辑“1”的输出，如果大多数输入为0，则产生“0”的输出。通过结合所提出的多数门电路，各种子系统可以构造有比布尔型构造更少的设备数量。作为例子，设计了加法器和奇偶校验发生器。计算机模拟表明，所设计的子系统产生正确的逻辑运算。对热扰动引起的操作误差也进行了估计。

In this project, we developed single-electron gate circuits based on the principle of the majority logic. The majority logic gate circuit proposed consists of a capacitor array for input summation and a single-electron inverter for threshold operation. It accepts an odd number of inputs and produces the corresponding output on the basis of the principle of majority decision; it produces an output of logic "1" if the majority of the inputs is 1 , and an output of "0" if the majority is 0. By combining the proposed majority gate circuits, various subsystems can be constructed with a smaller number of devices than that of Boolean-based construction. An adder and a parity generator are designed as examples. It is shown by computer simulation that the designed subsystems produce the correct logic operations. The operation error induced by thermal agitation is also estimated.
