In this work we analyze the effects of electromagnetic-induced interferences conveyed at the input of a transimpedance CMOS operational amplifier. In particular, it will be highlighted that transimpedance amplifiers natural exhibit a lower EMI susceptibility compared to common voltage-feedback opamps. Moreover, it will be shown through simulations that a careful circuit design can lead to opamps with a practically vanishing EMI susceptibility.

Abstract
In this work we analyze the effects of electromagnetic-induced interferences conveyed at the input of a transimpedance CMOS operational amplifier. In particular, it will be highlighted that transimpedance amplifiers natural exhibit a lower EMI susceptibility compared to common voltage-feedback opamps. Moreover, it will be shown through simulations that a careful circuit design can lead to opamps with a practically vanishing EMI susceptibility.File in questo prodotto:
