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。 Aiming at the problem that the readout current of EEPROM memory cells needs to be accurately detected, this paper proposes a circuit to detect the operating current of EEP-ROM memory cells, which is mainly constructed by current mirrors , And read out the circuit connected to the sense amplifier. In the test with the current mirror circuit to read Lingshi read current mirror current output of the output. Simulation results show that using this detection circuit to detect the read current can achieve higher accuracy (98.5%). At the same time, the circuit itself is simple, easy to implement in practice.
