The diffusion current is measured using transistor and digital ammeter instead of operational amplifiers, and the Boltzmann constant is obtained accurately. 在不使用运算放大器的情况下,直接利用晶体三极管与数字式电流表测出扩散电流,可以得到较为准确的玻尔兹曼常量。
Under careful consideration by using three parameters, base width, base diffusion length, base diffusion coefficent of a transistor, the program provides excellent calculating results of ultra phase-shifting factor. 根据决定晶体管性能的关键参数,如:基区宽度、基区少子扩散系数和基区少子扩散长度等,对晶体管超相移因子进行计算,得到精确的结果。
