基于过采样技术提高SOC单片机片内A/D分辨率的研究与实现

Resolution Improvement of ADC in the MCU by Using the Oversampling and Mean Value Technology

叙述了基于过采样技术,使用软件方法提高单片机片内A/D分辨率的基本原理及实现方法。给出了一个实现示例,将C8051F040片内12位分辨率ADC提高到16位分辨率。

This paper introduces a simple method that improves ADC resolution using software. By over sampling methods, the accuracy for C8051F040 microprocessor with on- chip 12 - bit ADC can reach that of 16 - bit ADC.
