自从晶体管问世之后,人们就注意到p-n结的温度特性,随着温度的升高,p-n结反向电流加大,正向压降减小,它是引起晶体管电路温度漂移的主要原因.从五十年代到现在,人们一直在从器件与线路两个方面努力克服这种影响.另一方面,一切与温度有关的物理过程又都可以利用来测量温度.利用p Since the advent of transistors, people have noticed the temperature characteristics of pn junction, with the increase of temperature, pn junction reverse current increases, the forward voltage drop decreases, it is caused by transistor temperature drift of the main reasons.From five From the decade to the present, people have been trying to overcome this effect both in terms of devices and circuits, on the other hand, all the temperature-related physical processes can be used to measure the temperature.Using p
