High-sensitivity 1-Gb/s CMOS receiver integrated with a III-V photodiode by wafer-bonding

We have developed a wafer-bonded hybrid receiver using 0.5-/spl mu/m CMOS that operates with a single 3.3-V supply voltage. The receiver circuit is small and simple, has high sensitivity and a broad bandwidth, and operates at either 0.85 or 1.55 /spl mu/m due to the direct attachment of the III-V photodiode without parasitic capacitance.
