| 摘 要： | 针对电可擦除编程存储器(EEPROM)存储单元的读出电流需要被精确检测的问题,该文提出了一种对EEP-ROM存储单元进行工作电流检测的电路,该电路主要用电流镜来搭建,和读出电路中的灵敏放大器相连。在检测时用电流镜电路把灵放的读出电流镜像到电流检测的输出端。模拟结果显示,用这种检测电路来检测读出电流可以取得较高的精度(98.5%)。同时,电路本身结构简单,在实际中易实现。

| Abstract: | Check circuit was developed to accurately measure the read current in an electronically-erasable programmable read-only memory (EEPROM) memory cell. This circuit includes a current mirror connected with the sense amplifier of the EEPROM read circuit. The read current can be precisely mirrored to the output by this circuit to measure the memory cell read current (precision reaches 98.5%). Simulations gave excellent results so the circuit can be widely applied. |
