触摸调光控制芯片的设计与测试

Design and TEST of the Touch Dimmer IC

电力作为一种方便的能源广泛应用于我们生活的各个方面,于是电能的节能变得尤为重要。由于家用照明设计可以从控制方面实现节能,因此人们可以根据自己不同时间的不同需要来调节灯光的亮度来达到节约电能的目的。本文提出了一种应用于家用照明亮度的调节控制芯片的设计方案,首先分析顶层模块的功能,再将其功能分类细化,分配到不同的子模块去实现,利用CMOS电压比较器来实现了过零检测、系统时钟脉冲产生、触摸控制等操作,并通过仿真软件验证了设计模块功能的正确性,最后经流片测试芯片功能满足设计要求。

Energy crisis is much more severe as the development of society.Scientific researches mainly focus on the way that may promote social development with limited energy resource.Electric-power is one of the most widely used power source,heighten electric device power consumption efficiency will lighten the crisis a lot.As different brightness is demanded at different situation,brightness control is one important way to save electric power under this situation.A design program of touch dimmer IC has been put forward for lighting brightness control in this paper.We studied the functions of top-level system first,and then divided them into different modules.We designed each module to realize the functions of zero-crossing detection,system clock generator and touch dimmer control.With the simulation software the designed module functions are verified.Finally,the test results for the processed IC meet the requirements of the touch dimmer application.
