The model and synthesis method of integrated linear attenuation network (LAC) used in mixed signal SoC for digital instrument are addressed in this paper. The model and synthesis method of the LAC used for electronics instrument is related with the application and implementation method. To the signal generator used in some electronics instrument, the LAC architecture could be linear and synthesized by resistor network and some additional circuits. Therefore, the spectrum properties of the LAC are relayed on the spectrum properties of additional circuits. The synthesis method is derived the formula of the LAC model. With the model, the integrated resistor network in the LAC used for measurement circuit module could be reduced. The LAC architecture synthesis method is suitable for the application of implementing a LAC with integrated circuit technology.
