最近制成了一系列温度零漂和时间零漂很小的运算放大器,但是为了放大1μV数量级和小于1μV的直流及亚低频电压,只能用带输入端信号调制的М-ДМ型放大器。放大器的特
Recently, a series of operational amplifiers have been developed with zero temperature drift and very little time drift. However, only М-ДМ amplifiers with input signal modulation can be used to amplify DC and sub-low frequency voltages on the order of 1μV and less than 1μV. Amplifier special
