Linear Attenuation Network Analysis and Synthesis

摘要

The model and synthesis method of linear attenuation network (LAC) used in the 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 resistor network in the LAC used for measurement circuit module could be reduced. The LAC architecture synthesis method is suitable for the using to implement the LAC with integrated circuit technology.
