Based on the 0.18 micron CMOS process, a two-stage Miller compensation operation transimpedance amplifier circuit was designed, the influence of temperature change on its performance parameters was studied, the temperature simulation analysis within the limit operating temperature range was completed, and the statistical performance analysis of the device parameter changes was carried out by using the process angle simulation method.The simulation results show that the main performance parameters of the op amp can meet the design indicators in the extreme temperature range, which proves the temperature adaptability of the circuit. Process angle simulation improves the reliability and performance range of the circuit.

In order to better target the protection of glass artifacts, this paper proposes a composition analysis and identification model of glass artifacts based on Bayesian and SVM, adopts a variety of analysis methods to extract and pre-process the data, establishes a composition analysis and identification model of artifacts and predicts the results for the next composition of glass artifacts, and finally validates the model, and the experimental results show that the SVM model obtains a high performance with high generalizability
