Fabrication of QDNVM‐based comparator

This work presents the fabrication of 1 bit comparator circuit based on quantum dot gate non‐volatile memory (QDNVM) for both analogue‐to‐digital and digital‐to‐analogue signal processing applications. The charge accumulation in the gate region varies the threshold voltage of QDNVM, which can be used as a reference voltage source in a comparator circuit. A simplified comparator circuit can be implemented using the QDNVM. In this work, the authors discuss the fabrication of QDNVM‐based comparators in designing analogue‐to‐digital converters and digital‐to‐analogue converters.
