A method is described comprising conducting a first current through a switching transistor. The method also comprises conducting a second current through a pair of transistors whose conductive channels are coupled in series with respect to each other and are together coupled in parallel across the switching...http://www.google.fr/patents/US8134548?utm_source=gb-gplus-shareBrevet US8134548 - DC-DC converter switching transistor current measurement technique
