Many projects require custom circuit design. Some projects need analog circuits, including motor control, audio, radio, and microwave. Other projects require digital design, including adding processors to existing projects, designing circuits involving field programmable gate arrays (FPGAs), and creating computer interface boards (using USB, serial, etc).

Many projects require both analog and digital design, often coexisting on the same board. In addition to the isolated design of the analog and digital sections and of the interface between them, these circuits have added difficulty because digital signals tend to carry across the backplane onto the analog half of the board, producing analog noise. Solving this requires careful design of the backplane.

STI has done projects involving all of the above and more, so if you need help with circuit design, please contact us today!
