Abstract
The circuit configuration has at least five single-electron transistors, three of which are connected via a second main node and a third main node between a first main node and an output. The fourth single-electron transistor is connected between the second main node and a first supply voltage, with its gate electrode being connected to the first main node. The fifth single-electron transistor is connected between the third main node and the first supply voltage, with its gate electrode being connected to the second main node. The circuit configuration is suitable for use as a full adder and as a multiplier.
