  • Low power drive circuit
    Patent number: 8228962
    Abstract: The invention relates to an integrated driver circuit suitable for driving a light emitter with a signal current I(time) based on a received signal said circuit comprising a differential pair of transistors having a first transistor and a second transistor each respectively forming part of a first branch and a second branch, said first branch comprises a node suitable for connecting to said light emitter and/or said first branch comprises said light emitter, wherein said second branch comprise at least one charge storage device. This charge storage device may be arranged to collect current otherwise wasted in the process of driving the light emitter. This current may be utilized to drive circuitry thereby reduce current consumption.
    Type: Grant
