Abstract: With the widespread application of touch technology, capacitive touch for button applications has shown a rapid development trend, and its anti-interference property has been increasingly concerned. A capacitive touch sensor controller with anti-interference capability is designed. The capacitive touch sensor controller can not only configure the charging and charge transfer timing arbitrarily, but also has the extended spectrum function. Simulation results show that the capacitive touch sensor controller has good flexibility and anti-interference property.

Key words: capacitive, extended spectrum, anti-interference, flexible
