Abstract: | 80 GHz operation has been attained for a divide-by-four frequency divider IC fabricated with non-self-aligned InP/InGaAs heterostructure bipolar transistors. To the authors' knowledge, this is the fastest digital frequency divider IC reported to date. The measured maximum toggle frequency of 80 GHz was the upper limit of the measurement setup |
