摘要 数模转换器是数字电子系统和模拟电子系统之间的常用接口电路。典型电压按比例缩放式结构的数模转换器可保证输出的单调性。分析典型的电压按比例缩放型数模转换器的工作原理,提出一种改进架构,从而降低了集成电路的制造成本。 The DAC is often used as input/output circuit of digital electronic system and analog electronic system. In the front and the end of the advanced electronics system, digital to analog converters (D/A converters) are applies to improve the performance of the digital processing technique. The representative voltage scaling DAC have the monotonic property of output. At first, I analyze the working theory of voltage scaling DAC, and then bring forward a new framework. It also has the monotonic property of output. It reduces the number of resistance and simulate switch. It retrenches the area of layout observably and reduces the working-cost of IC. The number of 8-bits voltage scaling DAC’s resistance reduces from 256 to 16.
