Implementation of Quantum Dot Cellular Automata (QCA) Based Logic Circuit in 4-Channel Capacitance to Digital Converter for Capacitive Sensing Solution

Abstract The capacitive sensing with grounded capacitor sensor is a very low power,low cost high-resolution contact-less sensing technique that can be applied to a variety of applications ranging from proximity sensing and gesture recognition to material analysis and remote liquid level sensing.As QCA based logic circuits have advantages in simulation time, area, less complexity, etc. It would be possible to get better output in such parameters by using QCA based logic circuits.

Keywords Capacitive sensing, QCA logic gate.
