引言为了提高晶体管的开关速度,希望晶体管线路接成共基极形式,而且使之不进入饱和区。另外,为使线路对收集结势垒电容和线路杂散电容充电时间减到最小,必须使线路讯号幅度减至最小。二极管网络可以完成逻辑操作,而且也很经济。但由于二极管是一种无源器件,在操作 INTRODUCTION In order to increase the switching speed of transistors, it is desirable that the transistor circuits be connected in a common base form and not be brought into saturation. In addition, in order to minimize the time it takes for the line to charge the collector junction barrier capacitor and line stray capacitance, the line signal amplitude must be minimized. Diode network can complete the logical operation, but also very economical. But because the diode is a passive device, in operation
