『Analysis and Design of Analog Integrated Circuits』
Analog integrated circuits (AICs) are circuits used for analog signal processing and are widely used in electronic devices such as audio, video, radios, etc. Generally speaking, the analysis and design of analog integrated circuits is quite challenging, requiring skillful integration of both "fabrication" and "circuit knowledge" to achieve optimal performance.
To start with, before designing a new AIC, a thorough understanding of signal processing requirements needs to be obtained and studied, including their complex interactions. At the same time, a range of circuit model parameters need to be considered and adjusted according to system requirements, to effectively compress the number of circuit nodes. Furthermore, diagnosis analysis diagrams can be used to determine the overall function of the circuit as well as to identify errors in design based on the required inputs and outputs of the system. In addition, component devices and their characteristics matching are essential to the analysis and design of AICs. Moreover, with the most advanced "circuit design tools", high-quality AICs can be designed.
Finally, the analysis and design of AICs may be a challenging task, but with system requirements in mind, a skilled designer can use circuit knowledge and advanced design tools to achieve optimal performance.
