Bipolar integrated circuit
In semiconductors, most carriers (holes and electrons) and a few carriers with two polarity participate in the conduction of active components, such as NPN or PNP bipolar transistors. The monolithic integrated circuits based on these transistors are called bipolar integrated circuits.
A monolithic integrated circuit based on the usual NPN or PNP bipolar transistors. It is the world's first integrated circuit made in 1958. Bipolar integrated circuit is mainly based on silicon material. On the basis of plane technology, it adopts buried layer technology and isolation technology, and bipolar transistor is the basic component. According to function, it can be divided into digital integrated circuit and analog integrated circuit. In the development of digital integrated circuits, there have been many different types of circuits. Typical bipolar digital integrated circuits include TTL, ECL and I2L. TTL circuit has developed earlier and its technology is more mature. ECL circuit has high speed, but high power consumption. I2L circuit is slow, but has high integrated density.
Compared with metal oxide semiconductor integrated circuit, bipolar integrated circuit is fast and widely used in analog integrated circuit and digital integrated circuit.
