The power supply is the foundation of a system, and a well-designed power supply is a prerequisite for stable system operation. In practical projects, the most commonly used power supply structure is an external adapter providing a DC input (5V, 9V, 12V, etc.). Various DC-DC or LDO chips are then used in PCB design to convert the input into the required power rails for the system. Therefore, we mostly deal with DC-DC and LDO power supply circuit design.

The packaging process is the last process of semiconductor manufacturing, and its sequence is grinding, cutting, pasting, wire bonding and molding. The sequence of these processes can be changed according to the change of packaging technology, and can also be closely related or merged with each other.

Today's signal processing systems generally need to use mixed-signal devices, such as analog-to-digital converter (ADC), digital-to-analog converter (DAC) and fast signal processor (DSP). In order to process analog signals with wide dynamic range, high-speed and high-performance ADC and DAC signals are more important.
