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,轨到轨放大器输出级增益与负载有关,这将影响放大器的开环增益,当然也影响了闭环增益的准确性。
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,通过对ota开环增益、单位增益带宽、相位裕度和建立时间等性能指标的分析,并对比了几种典型运放结构,设计开发了一种cmos全差分共源共栅两级运算放大器框架。
百科解释
The open-loop gain of an operational amplifier is the gain obtained when no feedback is used in the circuit.
