FLEXIBLE MULTI-VALUED HALF ADDER USING SINGLE ELECTRON LOGIC DEVICE

摘要

A convertible multi-valued half adder using a single-electron logic device is provided to increase the degree of integration by reducing the number of devices for constructing a half subtractor by 5. A single-electron logic device and a field effect transistor are formed in series to perform the SUM operation. 2 single-electron logic devices and the field effect transistor are formed parallel to perform the CARRY operation. A half adder circuit is formed by connecting an input gate 1 for the SUM operation with an input gate 1 for the CARRY operation, and connecting an input gate 2 for the SUM operation with an input gate 2 for the CARRY operation. The half adder circuit is formed by applying a voltage one of control gates A, B(33,34) of the CARRY operation.
