Current behavior analysis of the single supply differential capacitive sensing

Differential capacitive sensing technique has gained popularity in capacitance measuring system due to its high symmetrical implementation, easy to be implemented using discrete components and has a characteristic of high linearity in its system. However, very few work has reported on the differenti...
