Patch integrated block, also known as integrated circuit block, is a miniature electronic device that highly integrates a large number of diodes, transistors, resistors, micro-capacity capacitors and other miniature components on a small piece of silicon.
The size of the silicon chip is usually the size of a mung bean or smaller, but in this small area, there may be thousands or tens of millions or even hundreds of millions of transistors integrated.
In this way, the integrated block can greatly save space, while improving the stability and reliability of the circuit. In addition, because of its small size, low power consumption and high cost performance, the chip integrated block has been widely used in various electronic devices.
