【Abstract】 In this paper, the low temperature DL, charactenstics of the silicon bipolar. transistors are studied both theoretically and experimentally. The temperature models of current gain of the silicon bipolar transistors with vari-ous emitter depthes and current levels are presented, and the temperature dependent base widening effect is discussed.更多还原
