Third , rail - to - rail amplifier output stages exhibit load - dependent gain which affects amplifier open - loop gain , and hence closed - loop gain accuracy 第三,軌到軌放大器輸出級增益與負載有關,這將影響放大器的開環增益,當然也影響了閉環增益的準確性。
Firstly , a two - stage structure for the ota is presented after comprehensive considerations on characteristics like open - loop gain , unity - gain bandwidth , phase margin and settling time . then the input and output topologies have been decided by comparing different structure available for this purpose 首先,通過對ota開環增益、單位增益帶寬、相位裕度和建立時間等性能指標的分析,并對比了幾種典型運放結構,設計開發了一種cmos全差分共源共柵兩級運算放大器框架。
open-loop gainとは意味:開ループ利得{りとく} open-loop gain meaning:[Electronics] The overall gain (ratio of output to input) of an open-loop device, such as an amplifier without feedback. Also see OPEN LOOP. open-loop gain перевод:коэффициент усиления (при) разомкнутой цепи обратной связи; коэффициент усиления разомкнутой системы
