Description

The signal acquisition amplifier is an important part of the soft X camera diagnosis system, which is installed in the PXI chassis in the form of board card to improve integration. Due to the poor quality and noise of the power supplied by the PXI chassis, the acquisition of weak signal would be interfered. In order to improve the quality of the power supply and reduce noise, this article mainly focuses on the optimization of PXI power supply, the power impedance and decoupling capacitor are analyzed; the EMI power filter is designed; resonance between power supply layer and ground layer in PCB are analyzed. The experimental results show that the noise of power supply is reduced and the stability of power supply is improved. (authors)
