Abstract :
A CMOS operational amplifier with high immunity to electromagnetic interferences is presented. It is based on an easy modification of the differential pair with active current load. The proposed input stage can be fabricated in standard CMOS technologies, and it neither requires extra mask levels, such as triple well, nor external components. Analysis and results are provided for very large interferences, which arise from the input pin.
