  • Abstract
    When subjected to electromagnetic interference, an operational amplifier will generate a DC offset. A thorough comparison between two approaches to reduce this offset is presented. Through mathematical deduction and simulations, it is shown that placing a lowpass filter at the input differential pair is superior to a double differential pair compensation topology
