Spread spectrum clocking applied to charge pump for conducted emission improvement in automotive
Franck Galtie, Christian Marot · 2008
The aim of this paper is, first of all, to make a status about the Conducted Emission (CE) level of devices integrating a charge pump, currently used in automotive Electronic Control Unit (ECU). Then, the spread spectrum clocking method, in order to reduce CE levels, applied to such device is studied and results are presented.
