  7. Abstract:
  8. Emergence of the implantable biomedical microsystems and personal area networks in recent years result in a new class of biomedical systems that requires data transmition in short range at various data rates. Performing with ultra low power consumption and long battery life are crucial in these systems. Therefore, designing low power radios for these systems is still an active research area. Ultera wideband systems are specially considered for implementations because of their potential characteristics.
    In this dissertation, different biomedical applications and data communication approaches are surveyed. Then, Different architectures of UWB receivers are reviewed. To implement a low power receiver, a new approach which is based on the response of a linear time variant system is presented that can be classified in super regenerative receiver family. First, a new Comprehensive approach is presented for analyzing these systems that unifies different modes of operation of super regenerative receivers and gains the optimum waveform for detection. Base on this analysis, three different architectures in different bands are introduced and suitable circuits are implemented for them. These receivers consuming 11, 13.5 and 8 pJ/b which are much better than recent reported systems
