最近TI公司报道了一种甚高性能的InP/InGaAs HBT,其f_(max)为180GHz,f_T为100GHz,电流密度为1×10~5A/cm~2。有效延迟时间(f_T/8πf_(max)~2)为0.2ps,这是已报道的共发射极InP/InGaAsHBT中的最小值。 这
Recently, TI reported a very high performance InP / InGaAs HBT with f max of 180GHz, f_T of 100GHz and current density of 1 × 10 -5 A / cm 2. The effective delay time (f_T / 8πf_ (max) ~ 2) is 0.2 ps, which is the smallest of reported co-emitter InP / InGaAs HBT. This
