Abstract

This paper describes the design of a dual-channel optical transceiver array realized in a standard 0.18 mum CMOS technology for the applications of high-speed digital interface. The transmitter drives a 2-channel VCSEL array at 2.5 Gb/s, equipped with the APC (5-15 mA) and AMC (4-20 mA_pp) loops for constant and reliable optical power outputs. Meanwhile, the receiver exploits the common-gate transimpedance amplifier, demonstrating 87 dBOmega transimpedance gain, 1.4 GHz bandwidth for 2 pF input parasitic capacitance, -18 dBm sensitivity for 10^-12 BER, and less than -20 dB crosstalk between TX and RX within the bandwidth. The whole 2-channel transceiver array chip dissipates 500 mW.
