Discussion of Circuits in Intelligent Cups

intelligent cups had been chosen as our favorite portable cups in our bags for a long time. Not only their smart volume, but also their multiple abilities were useful to everyone. In this paper, several circuits were discussed according to their different functions. Some circuits were used as signal amplification functions. Some ones were used as transmission of electromagnetic wave signals. Some ones were use as fingerprint identification. These functions were components of the whole circuits. In these components, energy absorption parts were important ones. According to different functions of varied circuits, some improvements could be done with different requirements. Certainly, 51 single chips were usually important in the whole circuits.
