It is noted that a special use of light-emitting diodes or other electronic elements that can transform electrical energy into radiation contributes to cooling an electronic circuit. As a physical requirement, this use inevitably reduces the maximal frequency range of the operation, and thus the frequency conditions and requirements must be proper. The idea came from a very basic circuit theory and we consider only a simple model. It is believed, however, that in view of the tempestuous rate of modern technological development, realization of the theoretical possibility can become possible, and thus this possibility should be kept in mind. It is also hoped that the example of a practically-oriented conclusion directly derived from an analysis in the “energetic” v-q (voltage-charge) plane will encourage circuit designers to use this analysis more.
