Abstract :
We propose a novel cross coupled differential receiver to be used as part of a low power inter-chip optical interconnect. The internal amplifier of the transimpedance first stage provides high gain without requiring large, capacitive input gates. The resulting transimpedance stage extends the bandwidth of the differential receiver when small photodetectors are used. Preliminary results indicate a bandwidth of 1.4 GHz with a power consumption of 10 mW in a 0.5 μm UTSiTM SOS CMOS process.
