It is designed to have a minimum gain of 9.0 dB with 40 percent minimum collector efficiency (>45 percent typical) on a 50VDC supply.

在50伏特直流电供电情况下，其最小增益为9.0dB，而最低集电极效率为40%（>45%的典型值）。

We try to obtain the common-base current gain a of the parasitic PNP transistor from the eloping profile of the collector region including the effect of buried-layer.

本文从包括埋层影响的集区杂质分布出发，求出了寄生PNP晶体管的共基极电流放大系数。
