摘要：A driving circuit for driving light emitting diodes includes a signal-extendingcircuit and a current sink. The signal-extending circuit is used for receiving an originaldimming signal and extending a duty cycle of the original dimming signal. The currentsink is coupled to the signal-extending circuit for generating a driving current for driving aseries of light emitting diode.
