EMI Immunity of the Nauta Inverter-Based Amplifier

This paper investigates the effect of Electromagnetic Interferences (EMI) on inverter-based analog amplifiers, as the Nauta operational transconductance amplifier (OTA). We show that, thanks to the their simple circuital topology that does not include current mirrors and differential pair, the inverter-based analog amplifiers have a much higher EMI immunity respect to the classical topologies: about one order of magnitude.
