  • Communication diode driver circuit
    Patent number: 7570235
    Abstract: A Communication Diode Driver Circuit (CDDC) for selectively illuminating communication diodes (CDs) in response to incoming digital data pulses with a LED drive current ILED(t) close to a nominal LED drive current IN therefor in a steady state operation of the CDDC. The CDDC includes a driver unit for driving the LED drive current ILED(t), and a closed loop feedback unit for continuously monitoring the LED drive current ILED(t) for providing a variable shift voltage SV(t). The driver unit includes a shift amplifier for combining a pulsed analog data voltage ADV(t) corresponding to incoming digital data pulses, and the shift voltage SV(t).
    Type: Grant
