PI simulation and optimization of microsystem based on ADS

Abstract： With the development of chip manufacturing technology and packaging technology, the device integration and signal speed inside electronic products continue to increase, and microsystems become an emerging form, which leads to increasing requirements for power integrity. Unreasonable power supply integrity design will bring great interference to power quality and signal quality, and even make the system collapse. In this paper, the power supply integrity of the designed multi-chip microsystem was simulated, and the PDN impedance was optimized by the collaborative decoupling of substrate and PCB decoupling capacitor network, which solved the contradiction between the limited space inside the microsystem and the large demand for decoupling capacitor, and ensured the power supply integrity of the microsystem.
