Paper Abstract

In resent publications we presented PIN photodiodes with a bandwidth of 600MHz implemented in low-cost 0.6μm BiCMOS technology. A new method to increase the response time of these PIN photodiodes is proposed here. This method was applied to design an optical fiber receiver with a maximum possible data rate of 2.5Gbit/s. In addition to the PIN photodiode attached to a transimpedance amplifier it also includes a decision circuit and a 50Ω output driver. The measured bandwidth of the receiver of 1.90GHz is sufficient for 2.5Gbit/s. At an optical wavelength of 660nm, a sensitivity of -17.0dBm was measured. At a supply voltage of 5V, the power consumption of the complete receiver is 171mW, from which the output driver requires 128mW. The overall chip size is 1154μm times 727μm.
