近几年来,单用一种工艺难于获得各种不同要求的性能,例如双极型电路速度比较高,导通电阻比较小,但功耗较大,而且输入阻抗比较小,比较适合于高性能的模拟应用;又如MOS电路能获得高的输入阻抗、低的功耗,但速度不够理想,比较适合于数字电路;I~2L能使集成度比较高……,在VLSI电路中主要集成的是标准的数字电路.由于VLSI技术的发展,把一个电子系统或于系统集成在一个硅芯 In recent years, a single process is difficult to obtain a variety of different performance requirements, such as the bipolar circuit speed is relatively high, the on-resistance is relatively small, but the power consumption is larger, and the input impedance is relatively small, more suitable for high performance Of the analog applications; Another example is the MOS circuit can get high input impedance, low power consumption, but the speed is not ideal, more suitable for digital circuits; I ~ 2L can make the integration of high ... ... VLSI circuit in the main integrated Is a standard digital circuit due to the development of VLSI technology, an electronic system or system integrated in a silicon core
