Construction of LC Filter Integrated Circuit and Analysis of Control System Function

As one of the important components of integrated circuits, inductors play an important role in filtering, energy storage and impedance matching in many fields, such as communication and manufacturing. However, the existing traditional filters are not highly integrated, and have the defects of large volume and high energy consumption. Therefore, in this paper, constructs an integrated square spiral inductor model based on MEMS technology by using a finite element simulation method. First, through the simulation analysis of performing the model, the inductance coefficient is calculated and we analyze the spatial electromagnetic field distribution characteristics, and then the functional rationality of the model is verified. It is used to build the LC filter and analyze the principle of different filtering functions. Second, based on Proteus simulation software, an integrated circuit single-chip microcomputer control system with an LC filtering function composed of square spiral inductors is built. Finally, through the analysis of the simulation results, the results show the LC filter integrated circuit constructed in this paper has the characteristics of low-pass, high-pass, band-pass and band-cease filtering functions, and can be associated with the external control system to realize the intelligent operation of the integrated circuit.
