摘要: We report self-aligned indium-phosphide double-heterojunction bipolar transistor devices in a new manufacturable technology with both cutoff frequency (f/sub /spl tau//) and maximum oscillation max/) over 300 GHz open-base breakdown voltage (BV/sub ceo/) 4 V. Logic circuits fabricated using these production integrated-circuit process achieved current-mode logic ring-oscillator gate delay of 1.95 ps an emitter-coupled static-divider 152 GHz, which closely matched model-based circuit simulations.
