摘 要：This dissertation begins by examining future wireless sensor applications and presenting the link asymmetry. The alternative architecture is then introduced and its operation principles explained. A step-by-step design procedure follows, accompanied by the implementation of a miniature biomedical implant transmitter as a design example. Potential challenges and mitigation techniques are also discussed. Key advantages of the proposed architecture include ultra low power consumption, simple circuitry (hence high reliability and low cost), and broad range of scalability. Measurement results of the biomedical example are subsequently presented, before a short conclusion is given in the end.
