Abstract
This paper presents the first published S-parameters of an Si/Si1-xGex /Si heterojunction bipolar transistor (HBT) measured under pulsed bias /pulsed RF conditions. Comparison is made ro those of an Si bipolar ju nction transistor (BJT) fabricated using the same mask set. Measuremen ts made over a 400 mu s pulse show how device self-heating dramaticall y affects the microwave-frequency response of the two devces. The resu lts emphasize the need for accurate characterization of microwave Si d evices in pulsed applications. (C) 1998 John Wiley & Sons, Inc.
