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.
