Abstract
A wideband high CMRR instrumentation amplifier is described. Based on a previously reported current-mode design, the improved amplifier features excellent CMRR performance of better than 60 dB up to 200 kHz with unity differential gain.
摘要
本文描述了一种宽带高共模抑制比（CMRR）仪表放大器。基于先前报道的电流模式设计，该改进型放大器具有出色的CMRR性能，在高达200 kHz的频率下，共模抑制比优于60 dB，且差分增益为单位增益。
