摘要

提出了一种用锁存式比较器代替传统的基于运放的比较器的幅度-数字转换器。通过采用锁存式比较器和重新排列决策控制电路，可以消除pvt相关的定时误差。此外，在低速和高速运行时，可以提高功率效率。为了提高转换过程的线性度，还开发了动态电流源，以获得最佳的决定系数。一个10位转换器的原型被设计为工作在40-kS/s，只有56。S-$\mu$W分别表示功耗。

Magnitude to Digital Converter with Latch-Type Comparator and Dynamic Switching Current Scheme

A magnitude to digital converter is proposed using a latch-type comparator to replace the conventional opamp-based comparator. The PVT-dependent timing error can be relieved by employing the latch-type comparator and rearranging the decision control circuits. Besides, the power efficiency can be improved within the low and high speed operations. For increasing the linearity of the converting process, a dynamic current source is also developed to obtain the best coefficient of determination. A prototype of 10-bit converter was designed to operate at 40-kS/s with only 56.S-$\mu$W of power dissipations, respectively.
