PURPOSE: A current sensing method for a current-mode dc-dc converter using an offset voltage cancelling circuit is provided to detect accurate current by compensating an offset voltage with a switch - capacitor integrator.;CONSTITUTION: In a current sensing method for a current-mode dc-dc converter using an offset voltage cancelling circuit, a current is duplicated through a MOS transistor through a current mirror. At this time, an offset voltage is compensated through a switch-capacitor integrator.;COPYRIGHT KIPO 2011
