Implementation of a DC-10Mb/s 0.5μm CMOS Laser Diode Driver
-
Abstract
A DC-10Mb/s laser diode driver,compatible with TTL and CMOS levels,is presented.The optical power corresponding to ‘1’ and ‘0’ can be set independently with resistors off-chip and stabilized with a closed loop.A novel peak-to-peak optical power monitor and stabilization mechanism is introduced.The circuit,fabricated in a CSMC 0.5μm mixed signal CMOS process,can provide 120mA maximum drive current and 0.6dB extinction ration fluctuation over -20～+80℃,which is independent of input pattern.-
