摘要：

The commonly used definition of cutoff frequency fT of bipolar transistors is predicated on the existence of 8 frequency domain in which the magnitude of the current gain, varies inversely with frequency. In the absence of such a domain, the definition is vague. The definition 1/fr=d/df[lm (1/β)] for f→O is proposed. Copyright © 1969 by The Instrtute of Electrical and Electronics Engineers, Inc.
