Design and Packaging of a Robust 120-GHz OOK Receiver Used in a Short-Range Dielectric Fiber Link

This letter presents the design of a 120 GHz receiver in 28nm CMOS with a replica biasing temperature compensation loop as part of a short-range Gbps communication link with a dielectric fiber. A comparison is made between different biasing methods for a millimeter-wave envelope detector to ensure reliable operation over an operating range from -40 °C to +200 °C. Also, a robust packaging is proposed using an on-chip antenna to couple with the dielectric fiber. The design is followed by verification with measurements.
