Calculated high frequency performance of an npn Si/sub 1-x/Ge/sub x/ HBT
The authors calculate the performance of an Si/sub 1-x/Ge/sub x//Si HBT (heterojunction bipolar transistor), including effects of major importance such as bandgap narrowing and collector high injection. A description of the mobility model used is included. The results indicate that very high performance is achievable in these devices, particularly with respect to figures of merit such as f/sub max/, which are strongly influenced by the base resistance. For devices with 1- mu m geometry, the authors predict f/sub max/=81 GHz and f/sub T/=71 GHz. Such devices should also offer excellent performance in digital circuits in which low base resistance is essential.<>
