It does not need any matched components to reach high cmrr and its bandwidth is not gain - bandwidth product limited 該結(jié)構(gòu)不需要任何精確匹配的電阻就能達(dá)到高的共模抑制比,并且其帶寬不受帶寬增益積的限制。
The simulation result shows that , the cmrr of current - mode instrumentation amplifier be able to reach 97db , and the psrr to 85db 儀表放大器的仿真結(jié)果表明,在沒有激光調(diào)阻技術(shù)支持下,本文設(shè)計(jì)的電流模儀表放大器的共模抑制比能夠達(dá)到97db ,電源抑制比能夠達(dá)到85db 。
