All background calibration techniques rely on a slow convergence towards a desired state over multiple iterations. With all types of calibration the digital circuitry benefits greatly from technology scaling. Its area and power overhead make up only a small percentage of the overall chip in modern ...

TIADC是一种并行交替型ADC,采用并行的结构能够大大提高系统的采样速率,但是由于各通道存在时间失配、增益失配和失调失配,3种失配严重影响了TIADC的性能,本文研究的是时间失配,不讨论另外两种失配误差。目前TIADC采样时间误差的校准方案主要有两种:基于已知输入信号的前台校准算法和未知输入信号的后台校准算法,前台校准算法...
