SECOND ORDER PREDISTORTER FOR A RETURN LASER TRANSMITTER |
摘要 |
The invention provides a second order predistortion circuit which reduces distortions generated by an optical return laser transmitter. The predistortion circuit uses emitter follower as a second order distortion generator. Controlling the emitter D.C. current, the level of second order distortion signals can be easily controlled over a wide range.This predistortion circuit can be confirmed with a digital control circuit for laser distortion compensation over temperature. |
