Abstract :

[en] This paper presents a robust CMOS Miller operational amplifier (OpAmp) that has high immunity to electromagnetic interference (EMI). The proposed robust CMOS Miller operational amplifier uses the modified replica Miller OpAmp concept with the source-buffered Miller OpAmp with source degeneration resistance in order to achieve high EMI immunity across a wide range of frequencies (10 MHz to 1 GHz). Simulation results show that the maximum EMI-induced input offset voltage for the proposed robust CMOS Miller OpAmp is less than 5mV over a wide range of frequencies (10 MHz to 1GHz) when a 1 Vpp EMI signal is injected into the non-inverting input. In contrast, the classic Miller OpAmp generates a maximum output offset voltage of 216 mV at 1GHz under the same operating conditions. © 2017 IEEE.
