Abstract :
The design of a 155Mb/s-4.25Gb/s laser driver in SiGe BiCMOS is described. A large output voltage compliance range that allows DC coupling to the laser diode is achieved with a translinear pseudodifferential output driver. Active back-termination is provided at the modulation output pins. Careful design of the level shift stage affords low deterministic jitter over a very wide range of bit rates. The dynamic performance is preserved over a wide range of modulation current with a segmented driver slice scheme.
