On off keying modulation/demodulation and its applications

Abstract

OOK based communication is getting more and more popular to reduce the power consumption of portable systems. Although OOK based communication requires less circuit complexity, high performance structures are needed. Most common methods used for OOK demodulation are envelope detection and production of the signal with itself. Envelope detection is simple with minimal power consumption meanwhile production usually requires mixers which requires much more power. This work provides design steps for various blocks in OOK communication based systems, especially demodulators. This work introduces two demodulator structures, one for 60 GHz pulse communication and the other for RFID tag chips. In addition, this work provides information about the systems as a whole as well as block based sections. Simulation and measurement results are provided when available.
