Abstract

A 10μV offset opamp obtained by analog trimming will be reported. The circuit has a 100MHz gain-bandwidth product and a 25V/μs slew rate, using feedforward and local positive feedback. Die size is 80×120mils, and input offset current is 6pA.
一种可调谐p沟道JFET四极运放
本文将报道通过模拟修整获得的一个10μV偏置运放。该电路采用前馈和局部正反馈,增益带宽积为100MHz,转换速率为25V/μs。芯片尺寸为80×120mils,输入偏置电流为6pA。
