Abstract
This paper is proposed on the transmit Method Finger-Printer Scanning of Mutual Capacitance Touch Screen Panel Using Differential Pulse for improving the security of computer information. This system is composed of differential pulse generator and Ring-Counter, also Supply voltage is 5V. this system generates the Pulse wave which is composed of In-Phase and Out of Phase at 1MHz while period of 2m/s. it is designed and be able to operate four channels. overall power consumption is approximately 78.08nW. This prototype is implemented in 0.25um CMOS Process and Chip area is $870um{\times}880um$.
