Description
Summary:This paper discusses the design of an optoelectronic integrated circuit (OEIC intended for optical recording systems. The electronic noise in the system is an issue for high-speed operation and dual-layer blu-ray discs. In order to get a good impression of the various noise sources in the system, a noise calculation model has been developed. The design of the photo-diode and the preamplifiers in a BiCMOS/CMOS processes is discussed. The advantage of CMOS downscaling on the speed race is reported. A novel low-noise, low-voltage and low-power CMOS topology is described. Furthermore, some preliminary results of a test OEIC in 0.18 /spl mu/m CMOS are also reported. The measured input-referred current noise is 350 fAHz/sup -1/2/ at 20 MHz equivalent with the shot-noise level generated by a photo current of 380 nA. The active area of the test die, excluding bonding pads, is 0.36/spl times/0.26 mm/sup 2/ and the power consumption is 12.5 mW from a 1.5 V supply voltage at room temperature.
