A dynamic frequency divider with 82.4GHz maximum operating frequency and a static frequency divider with an operating frequency of 60 GHz was reported for use in future millimeter-wave systems. Fabricated using self-aligned, selective epitaxial growth (SEG) SiGe heterojunction transistors (HBT), they provide a cut off frequency of 122 GHz, a maximum operating frequency of 163 GHz, and 5.5ps emitter coupled logic (ECL) gate delay. The transistor characteristics, schematic diagrams and frequency and current characteristics of the devices were described.
