摘要
介绍了一种具有可编程阈值电平和偏移补偿的轨对轨差分输入级。讨论了微分比较器和双微分比较器的实现应用。在MOSIS 0.5 μ m CMOS技术测试芯片上获得的实验结果表明,在1.5 V电源电压下,可以验证轨道到轨道的运行。
An Input Stage for the Implementation of Low-Voltage Rail to Rail Offset Compensated CMOS Comparators
A rail-to-rail differential input stage with programmable threshold levels and offset compensation is introduced. Applications for the implementation of differential and double differential comparators are discussed. Experimental results obtained from a MOSIS 0.5 mum CMOS technology test chip are shown that validate rail-to-rail operation with a 1.5 V supply voltage.
