30–39GHz 2Gbit/s ring oscillator based OOK-modulator for chip-to-chip communications

This paper presents a 30–39GHz 2Gbit/s OOK modulator targeted for chip-to-chip communications. The design is based on a 10 to 13 GHz ring oscillator with three times frequency multiplier, and an embedded 2 Gbit/s data feed. The detailed circuit description as well as analysis to estimate the effect of component mismatches to both ring oscillator and frequency multiplier performance is given in this paper.
