This paper introduces a new application of microwave oscillator using magnetostatic wave (MSW) waveguide. The presented device operates as a wide-band tunable microwave detector with high sensitivity utilizing the super-regenerative principle. The circuit is composed of single active microwave device and several passive components including the MSW waveguide to define the operation frequency. On the circuit, the detection signal of 0.1V P-P with S/N 20dB is obtained as a response to the input signal with 28kHz 100% on-off keying of -43dBm at 2GHz. Moreover, by the nature of the MSW, the linear tuning over 800MHz is realized. The simplicity and tunability should be useful for various industrial and commercial applications.

“…Indeed, the core of the oscillator often requires a simple amplifier to compensate resonator losses and could operate at low bias current. However in narrow band communications, such architecture suffers from a lack of frequency selectivity which is always many times larger than the maximum data rates [5]. This excessive reception bandwidth makes the receiver more sensitive to noise and interference compared to other systems.…”

Over the recent past, super-regenerative architecture has been used for narrow band systems, dedicated to ultra low power applications. This paper aims to demonstrate the interest of this architecture for impulse UWB signals. First, it shows that, for a given mean power, superregenerative receiver is more efficient for impulse signal than for narrow band signal. After reminding the general theory of such receivers, it highlights how the architecture can be matched to the UWB signal in order to optimize detection performance. At last, BER curves based on simulation results are drawn for realistic UWB channel model. It shows that we can reach working point compatible with UWB low power applications and opens the door to a new class of UWB receivers.

“…There is a significant amount of literature, such as [33,46,76,77,78] targeted at the reduction of communication energy of wireless sensor networks (WSNs) and the increase of system battery lifetime. However, interference robustness is not addressed that much even though communication in most WSNs takes place in the largely crowded ISM frequency bands [27].…”

Wireless sensor networks (WSNs) have the potential to build breakthrough technologies for a variety of applications to improve human life. Some of the important applications are prevention, prediction and rescue of disasters, medical study and cure, improve the energy efficiency of homes and industries and study environments in remote places. These applications desire an ultra low power sensor node to extend the battery life, so that minimum or zero maintenance is required after initial installation. With the advancement of CMOS technology, power consumption of processors and semiconductor memories has reduced drastically. However, the radio transceiver power consumption has not experienced much power reduction because of its RF analog circuits. This makes the transceiver the bottleneck with respect to lifetime in existing sensor nodes. Another growing challenge for the sensor node transceiver is its interference robustness. Therefore there is a need of ultra low energy and interference robust wireless transceivers to enable WSNs to thrive in several applications which are not yet successful. This thesis targets an energy optimized and interference-robust radio communication system for WSNs. Special focus is given to the receiver, as the receiver is either always ON or ON for more time than the transmitter for duty-cycled radio and hence it is the critical part of the transceiver performance both in terms of power reduction and interference mitigation. A system level optimization of the transceivers is carried out, and circuit techniques are proposed to reduce the receiver power consumption. sensornetwerken gebaseerd op andere communicatiestandaarden te verbeteren. v Contents Contents vii List of Figures xi Nomenclature xiv acknowledgement xiv B.1 Chirp synchronization circuit block diagram for the chirped-LO
