| Abstract(in English) | Two-dimensional simulations of cutoff frequencies for AlGaAs, GaAs HBTs with an ideally insulating external collector are made, and the results are compared with those for a case with a semi- insulating external collector and for a case with a normal n^- external collector.It is found that in a case with an ideally insulating external collector,minority carriers injected into the base from the emitter are partially blocked by the insulating layer and accumulate in the external base layer.These carriers increase the effective base delay time,resulting in a remarkable degradation of the cutoff frequency.In relation to this effect, collector-up,HBTs are also simulated,and the design criteria for them are discussed.It is concluded that the effective emitter width should be narrower than the collector width. |
