    Dr. Peters’ thesis deals with the conception, development, and characterisation of novel components for an improved wireless power supply as exemplified by a biomedical osteosynthesis sensor system. In the last few years the demand for telemetric power supply, which is used in hard accessible systems such as biomedical implants, has steadily increased. In the doctoral thesis novel and better functioning components for telemetric power transmission such as multi-wire coils and AC/DC converters are presented. The main objective is the design of fully CMOS-integrated highly efficient rectifiers. Two approaches have been developed and characterised: one based on active rectifiers and the other based on floating gate rectifiers.

     

    The active rectifiers examined in the thesis were able to reach a measured and verified efficiency of above 90%. The floating gate rectifier version shown here for the first time allows for a very efficient application of robust high voltage transistors even with low input voltage amplitudes. Additionally, an analytical algorithm for multi-layered multi-wire coils has been introduced and verified so that for the first time it is possible to calculate the inductance of multi-layered multi-wire coils with an error of less than 10%.
