A PSK-demodulator for a bi-directional data transmission in passive telemetric microsystems is presented in this work. These systems, which use the telemetry link for energy and data transmission, are based on identification systems, which use ASK-modulation for both data transfer directions. This leads to problems with a bi-directional data transmission in sensor applications, where the power consumption...
Rectangular micro coils which are used in a wide range of applications (e.g. medical or automotive area) are the main components of appropriate wireless transmission systems for frequencies up to 20MHz. As shown in previous works the self-inductance of micro coils has to be maximized to achieve a higher working distance. This can be done by the usage of a permeable layer underneath the micro coil...
