Abstract
Different Input Topologies with resistance to electromagnetic interferences EMI are analyzed and compared in terms of EMI reduction The emphasis in this study is put on circuit robustness and applicability to industrial applications which requires sufficient EMI rejection over all process corners Furthermore a new topology based on a replica amplifier is introduced that is more robust to process variation compared to previous works JeanMichel Redouté and Michiel Steyaert ESSCIRC Sept 2008 Fiori IEEE Transac Electromag Compat 494834–839 2007 that rely on accurate matching of absolute values in order to achieve efficient EMI cancellation
