Abstract
In one embodiment of the present invention, an electronic device comprises a circuit board having a first side and a second side and having circuit traces formed only on the first side. The electronic device further includes a voltage regulator providing a regulated voltage via a regulated voltage output terminal and having a regulated voltage return terminal. Additionally, the electronic device includes a microcontroller mounted to the first side of the circuit board and having a plurality of regulated voltage input terminals and corresponding microcontroller voltage return terminals. The electronic device also comprises a bus comprising a first circuit trace coupled to the regulated voltage output terminal and a second circuit trace coupled to the regulated voltage return terminal, the first circuit trace and the second circuit trace running substantially parallel to one another. Furthermore, the electronic device include a plurality of supply conductors, each coupled to the first circuit trace and to one of the regulated voltage input terminals; and a plurality of return conductors, each coupled to the second circuit trace and to one of the microcontroller voltage return terminals. Designs according to the present invention can provide excellent radiated emissions performance with an economical single-sided circuit board and a minimal number of T-filters.
