In this paper, a two-stage inverter-based operational transconductance amplifier (OTA) is presented and investigated in terms of Electromagnetic Interference (EMI) susceptibility, by comparing it against the well-investigated topology of the twostage Miller OTA. Post-layout simulations demonstrate higher EMI immunity for the inverter-based amplifier by approximately one order of magnitude, due to their simple and symmetric circuital topology without current mirrors, differential pairs and current biasing.

Abstract
In this paper, a two-stage inverter-based operational transconductance amplifier (OTA) is presented and investigated in terms of Electromagnetic Interference (EMI) susceptibility, by comparing it against the well-investigated topology of the twostage Miller OTA. Post-layout simulations demonstrate higher EMI immunity for the inverter-based amplifier by approximately one order of magnitude, due to their simple and symmetric circuital topology without current mirrors, differential pairs and current biasing.File in questo prodotto:
