由于线性电路品种繁多,线路较逻辑线路复杂,而对于每一台设备所用量又不是那么多,所以,线性电路没有像逻辑电路那样较快实现产品的规格化和投入大量生产;另外,由于平面工艺的限制,制造电感、大电容、大电阻和PNP晶体管较困难,在制造元件上的制造公差也较大,所以,线性集成电路发展初期落后于逻辑集成电路。 Because of the wide variety of linear circuits, the complexity of circuits, and the less amount of equipment used for each device, linear circuits do not have to be more standardized and put into mass production as fast as logic circuits. In addition, Process constraints, the manufacture of inductors, capacitors, large resistance and PNP transistors more difficult, manufacturing tolerances in manufacturing components are also larger, so the initial development of linear integrated circuits behind the logic integrated circuits.
