Abstract

A 3.8-Gb/s laser driver with automatic power control (APC) using thermistors is presented. The chip was fabricated in 0.25mum 1P5M CMOS process. With a waveform shaping circuit, the driver could generate a 5mA to 60mA modulation current with its duty cycle maintained at 50%. A modified MUX circuit is also introduced to improve the jitter performance of both the direct and latched data output. And with a thermistor-APC compensation circuit, the laser power could be maintained within a temperature range from -30 degC to 80degC without using any monitor photodiode. Measurements on mounted chips show clear electrical eye diagrams operating over 3.8-Gb/s data rate with typical rise/fall times (20% to 80%) of 104/109ps. Moreover, an optical eye diagram is also demonstrated by connecting the driver with a 2.5-Gb/s 1310nm laser diode.
