Packaging means that the circuit pins on the silicon chip are wired to the external connectors for connection with other devices, or it refers to the housing used to install semiconductor integrated circuit chips. It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also is connected to the pins of the shell of package by wi...

At present, global network service giants such as Google, Microsoft, Facebook, and Amazon begin to enter the independent research and development of chipset solutions, and invest heavily. In 2017, Amazon spent $22.6 billion on research and development, up 41% from 2016, and quite a few of it was used to design customized artificial intelligence chips. Alphabet, Intel, Microsoft and Apple also foll...

1. What is BJT TransistorBJT transistors are three-terminal active devices made of two PN junctions, which are interacted with each other and fabricated on single crystals of semiconductor germanium or silicon to form a PNP (or NPN) structure. The N-type region in the middle is known as the Base (B), and the P-type regions on both sides are known as the Emitter (E) and the Collector (C), each of w...

MOSFETs are widely used in switching power supplies due to their low internal resistance and fast switching speed. The MOSFET often selects a appropriate driver circuit based on the parameters of the power-supply IC and MOSFET. Let's discuss the drive circuits of MOSFETs for switching power supplies.When using a MOSFET to design a switching power supply, most people will consider the parameter...

The mastery of analog circuits is divided into three levels:Primary level: Skillfully memorize the twenty circuits and understand their roles. Both electronics lovers and electrical and electronics engineering majors, should and could remember these twenty basic analog circuits.Intermediate level: Can analyze the role of key components in these twenty circuits, what are the effects on the function...
