The article suggests methods for improving the quality of analysis of electronic devices. Using the electromagnetic field theory and the theory of electrical circuits within the system allowed to combine research and schematic structural and technological design of electronic systems and their components. To illustrate the proposed approach chosen amplifier circuit. The model reproduces the design features of the PCB in the form of electromagnetic design parameters.
