Paper Abstract

In this paper, an integrated optical receiver module with demultiplexer chip-to-chip optical interconnects is proposed. The receiver and demultiplexer (demux) were realized on a single chip in a 0.18 μm TSMC CMOS technology. The topology uses a 1:2 for the demux while the receiver (Rx) module consists of transimpedance amplifier (TIA) and a limiting amplifier (LA). The receiver achieved a gain of 90 dBΩ and a 3-dB bandwidth of 4.5 GHz. Clear eye diagrams were observed with a voltage swing of 375 mVpp up to 2.5 Gbps output from the Rx-Demux at 5 Gbps input signal. The integrated chip occupies an area of 594x1089 μm2 with power consumptions of 122 mA under a 1.8 V power supply This solution could be applied to CPU/memory interface where bidirectional signaling is required.
