摘要

摘要本文对不同集成运算跨导放大器(OTA)拓扑结构的EMI易感性进行了比较研究。我们分析了基于Miller OTA和具有较低功耗的折叠级联概念的传统众所周知的放大器拓扑。给出了电源和输入共模高频扰动引起的输出直流电压偏移。在EMI磁化率比较的基础上,我们用一种新的模拟装置讨论了大激励信号和小激励信号中的PSRR和CMRR。此外,还研究了OTA输入级中差分MOS对的背栅连接对EMI易感性的影响。

An EMI susceptibility study of different integrated operational transconductance amplifiers
Abstract This paper presents a comparative EMI susceptibility study of different integrated operational transconductance amplifier (OTA) topologies. We analyzed conventional well-known amplifier topologies based on the Miller OTA and folded cascode concepts with lower power consumption. The output dc voltage shifts induced by power supply and input common mode high frequency disturbances are presented. On top of the EMI susceptibility comparison, we discuss PSRR and CMRR within large and small excitation signal with a new simulation setup. Even more, the back-gate connections of differential MOS pair in OTA input stage are investigated for EMI susceptibility impact as well.
