Abstract
We present an optical fiber receiver which includes a monolithically integrated PIN photodiode, a transimpedance amplifier, a decision circuit and a PECL compatible output driver. This low-cost and low-power receiver was fabricated in 0.6μm BiCMOS technology. Only one minor process modification was necessary to implement the PIN photodiodewith a diameter of 150μm. A minimum number of external components is needed for interfacing with standard PECL gates. At a maximum possible data rate of 625Mbit/s, a sensitivity of -22.7dBm was measured at an optical wavelength of 660nm. At a single-supply voltage of 5V, the power consumption of the complete receiver is less than 74mW. The overall chip size is 1763μm times 648μm.
