High-speed operation of static binary frequencydivider using resonanttunnelling diodes and HEMTs

A new circuit technology using resonant tunnelling diodes and HEMTs makes the toggle frequency ftoggle of a static binary frequency divider close to the cutoff frequency ft of the used 0.7 µm-gate HEMTs. ftoggle and ft are 34 and 38 GHz, respectively. This technology is promising for use in high-speed logic circuits.
