电学中的测量技术涉及范围非常广,电流测量在电学计量中占有非常重要的位置。如何精确地进行电流测量是精密测量的一大难题。传统的电流检测电路多采用运算放大芯片与片外电流检测电路相结合的方式,电路集成度很低,需要较多的接口和资源才能完成对电路的检测。本文把所有电路部分都集成在一块芯片上,包括检测电阻,运算放大器电路及模拟转数字转换电路,从而在电路内部可以进行电流检测,使电路更好的集成化。前置电路使用二级共源共栅结构的运算放大器,减小沟道长度调制效应造成的电流误差。10位SAR ADC中采用电容驱动能力强的传输门保证了模数转化器的有效精度。比较器模块采用再生锁存器与迟滞比较器作为基础单元组合解决精密测量的问题。本设计可以作为嵌入芯片内的一小部分而检测芯片中的微小电流1mA~100mA,工作电压在1.8v左右,电流检测精度预期达到10uA的需求。The measurement TECHnology in electricity involves a wide range,and current measurement plays a very important position in electrical measurement.How to accurately measure current is a big problem in precision measurement. The traditional current detecting circuit adopts the combination of the operational amplifier chip and theoff-chip current detecting circuit, The circuit integration is very low, and more interfaces and resources are needed tocomplete the circuit detection.This topic integrates all the circuit parts into one chip, including detection resistance, operational amplifier circuit andanalog to digital conversion circuit. Highly integrated circuit makes the external resources on the chip more intensive,so that current detection can be carried out inside the circuit, so that the circuit can be better integrated. Thefront-end circuit of this project uses two-stage cascade operational amplifier and cascade tube to reduce the currenterror caused by channel length modulation effect. In 10-bit SAR ADC, the transmission gate with strong capacitivedriving ability ensures the effective accuracy of the analog-to-digital converter. Comparator module uses regenerativelatch and hysteresis comparator as basic unit to solve the difficult problem of precision measurement. This topic can beused as a small part of the embedded chip to detect the micro-current in the chip 1 mA~100 mA, the working voltageis about 1.8v, and the current detection accuracy is expected to reach the requirement of 10 uA.

1前言1.1电路仿真分析软件简介电路仿真（simulation）分析软件很多，有用于模拟电路的、有用于数字电路的、有既可以用于数字电路也可以用于模拟电路的，而且在这些软件中，有的功能非常强大，用户使用起来很方便、并且容易入手，而有些就要逊色多了，在这里就不一列举那些软件以及它们的功能，用户可以根据实际情况选择适合的。当然商用的电路仿真软件往往功能强大，但价格也非常之昂贵，而用于学习的免费软件功能就弱多了。LTspice是集成电路仿真分析软件其中之一，它是一个可视化的图形输入电路仿真软件，在windows操作系统下运行。下面就主要介绍LTspice的功能、特点和使用方法。Linear TECHnology公司是一家大型的美国电子元器件制造商，它生产各种各样电子元器件，有模拟电路元器件、有数字电路元器件等等。1.2电路仿真软件做什么？电路仿真软件主要用于分析电路的功能和性能。当我们仿真分析电路时，首先必须明确你要仿真分析的电路是模拟电路还是数字电路，这是因为模拟电路和数字电路需要分析的功能和性能有所不同。
