A 0.25 \mum InP DHBT 200 GHz+ Static Frequency Divider.

Static frequency dividers are widely used technology performance benchmark circuits. Using a 0.25\,\mu\ m 530\,GHz f T/600\,GHz+ f \max InP DHBT process, a static frequency divider circuit has been designed, fabricated, and measured to operate up to 200.6 GHz refid="ref1"/ . The divide-by-two core flip-flop dissipates 228 mW. Techniques used for the divider design optimization and for selecting variants to maximize performance across process changes are also discussed.
