摘要
介绍了多晶硅电阻非线性度对信号链整体电路性能的影响, 分析了多晶硅电阻非线性产生的原因。提出了衬底电位补偿和组合多晶补偿两种非线性补偿设计方法。采用仿真和测试, 对比了未经补偿、新补偿方法的12位D/A转换器的性能。结果表明, 经过多晶硅电阻补偿和非线性补偿后的D/A转换器达到了更优的线性度。
Abstract
The influence of the nonlinearity of polysilicon silicon resistance on the overall circuit performance of signal chain was introduced, and the causes of the nonlinearity of polycrystalline silicon resistance were analyzed. Two nonlinear compensation design methods, substrate potential compensation and composite polysilicon compensation, were proposed. The performance of 12 bit D/A converter without compensation and with the new compensation method were compared by simulation and test. The results showed that the D/A converter with polycrystalline silicon resistance compensation and nonlinear compensation achieved better linearity.
