一种抗干扰的电容式触摸传感控制器设计

Design of an Anti-Interference Capacitive Touch Sensor Controller

随着触控技术的广泛应用,用于按键应用的电容式触控呈快速发展趋势,其抗干扰性也愈发受到关注。设计了一种抗干扰的电容式触摸传感控制器,该电容式触摸传感控制器不仅可以任意配置充电及电荷转移时序,还具备扩频功能。仿真结果表明,该电容式触摸传感控制器具有良好的灵活性和抗干扰性。

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.
