This paper presents a 24 channel capacitive touch sensing ASIC. This ASIC consists of analog circuit part and digital circuit part. Analog circuits convert user screen touch into electrical signal and digital circuits represent this signal change as digital data. Digital circuit also has an I2C interface for operation parameter reconfiguration from host machine. This interface guarantees the stable operation of the ASIC even against wide operation condition change. This chip is implemented with 0.18 um CMOS process. Its area is about 3 $mm^2$ and power consumption is 5.3mW. A number of EDA tools from Cadence and Synopsys are used for chip design.

In this paper, the method of the stability test of the Two-Dimensional digital filters is developed. The Liepunov's stability theorem of One-Dimensional discrete system is extended to Two-Dimensional digital filter transfer function which can be transformed twodimensional state space representation. The results developed above is agreed with of mapping method.
