Abstract
The emerging Medical Device Radiocommunications (MedRadio) service has been developed over the past decade to build up a more flexible and comfortable medical care system. In order to take the advantage of MedRadio, a low-power, compact, reliable as well as low-cost wireless transceiver is necessary. Unfortunately, low carrier frequency usually leads to either the utilization of bulky off-chip components or the high power consumption of inductorless design. It is still a challenging task to design a transceiver suitable for MedRadio applications.
In this thesis, a low-power, size-reduced and highly-integrated transceiver along with high speed data transmission is developed for diversified MedRadio applications. In Chapter 3, by employing the feedback loop, both the noise and current consumption of the proposed receiver is effectively reduced while maintaining a good input impedance matching. In Chapter 4, with fast data switching cells and radiation power control mechanism, the proposed transmitter achieves fast start-up and energy-efficient characteristics. In addition, the transmitter drives 50-Ω load directly enabling the integration of commercialized antenna. In Chapter 5, with monopole antennas and renewable energy supplier, the complete wireless link using implemented receiver and transmitter is established and demonstrates data-in data-out functionality.
