  • Abstract
    This paper explores SiGe profile optimization for improved cryogenic operation at high injection. Through analyzing distributive transit time profiles, the bottle neck limiting high injection fT is identified and then eliminated in an optimized profile design. The fabricated profile indeed shows considerably improved fT and beta at high injection
