Based on a 100 nm metamorphic HEMT process with 220 GHz transit frequency fT an optimised dynamic 2:1 frequency divider has been designed. A consequently implemented symmetrical design and optimised three-metal interconnect technology with BCB dielectric layer results in a very small core size which leads to a maximum operation frequency of 108 GHz.
