In a new study, researchers constructed a one-bit comparator using quantum dot cellular automata nanotechnology.

Designed for power management applications in battery operated circuits, the TC1031 combines a low power voltage reference with a programmable hysteresis comparator and shutdown in a single 8-pin ...

Each bit is encoded using the magnetic field of a single atom — making for extremely compact data storage, although researchers have stored only two bits of data so far.

Here, the reversible low power n-bit binary comparator has been designed. The two new reversible gates namely BJS and HLN gates are used to design an n-bit binary comparator.
