Design of Simultaneous Bidirectional CMOS Transceiver with a Resistor Transconductor Hybrid for Optical Chip-to-Chip Interconnects

摘要

A simultaneous bidirectional CMOS transceiver for foll duplex chip-to-chip optical interconnects is proposed, utilizing a resistor-transconductor (R-gm) hybrid. The hybrid separates the inbound signal from the input/output compound signal. The simultaneous bidirectional CMOS transceiver is designed in a 0.18 μm Si-CMOS technology, with power dissipation of 79 mW and 54.4 mW for the transmitter and receiver, respectively. It shows a 3-dB bandwidth of 4.6 GHz for both the transmitter and the receiver with a 3-dB gain of 26.6 dB and 10.6 dB, respectively, in foil-duplex mode.
