摘要
介绍了一种用在模拟电路中修调的EEPROM电路.该电路采用一种新型的单层多晶EEPROM结构,与传统的双栅EEPROM结构相比,该结构与数字CMOS工艺兼容,成本低、成品率高.使用在一个基准电压电路中时,其基准电压的调节范围达到±4.82%,调节精度达到4mV.EEPROM修调电路可广泛应用于各种高精度需求的电路中.
A new EEPROM circuit for analog trim is proposed.Comparing with the traditional double-gate EEPROM structure,the new EEPROM structure is not only with standard CMOS processes but also has low cost and high yield.When used in the voltage reference circuit,this circuit can achieve a voltage range about±4.82%,and a precision about 4mV.This circuit also can be widely used in the high precious required circuits.
