A Compact 130 GHz CMOS OOK-Doubler with Embedded 10 Gb/s Modulator and Integrated Glass Antenna for Scalable Array Systems and Efficient Short-Range Communication

This paper presents a D-band on-off keying (OOK)-Doubler that uses a balanced push-push design with an integrated switch at its common-node (CN) for second harmonic modulation. The input impedance of the proposed modulator remains almost constant with less than 1% mismatch during the switching states of the direct modulation. The design of the circuit is realized using the 65 nm CMOS TSMC process, featuring a compact size. It is heterogeneously combined with a glass antenna that employs General Electric's Fused Silica technology, achieving a gain of 6dBi. The integrated OOK-doubler and glass antenna achieves up to 10Gb/sec data rate over 7 cm, with BER of 10-6. The chip consumes 14-mW DC power with saturated power of -2 dBm.
