分析了一个应用于测量的 16位精度开关电容Δ2Σ模数调制器. 该调制器采用 3阶 1位单

环包含局部谐振器的前馈结构 ,在保证其具有较大的输入信号允许范围的同时引入零点优化来提高信号 /噪声失真比. -Analysis used to measure a 16-bit precision switched-capacitor modulator Δ2Σ modulus. The 3-order modulator using a single ring resonator, contains the local feed-forward structure, ensure that it has a large range of input signal at the same time allows the introduction of zero optimization to improve the signal/noise and distortion ratio.
