Abstract

This study presents a readout circuit, which senses the coupled electric hum signal through fingers, for touch screen panel applications. By sensing the electric hum signal, the transmitter circuit is not required in the touch screen panel system. A 16-channel readout prototype was implemented by using 0.18-pm CMOS technology. The experimental results show that the proposed readout circuit can recognize the touched-position by sensing the electric hum signal. The power consumption is only 2 mW.
