An ephemeral network is usually defined by the very short-lived and heterogeneous nature of interactions among self-organizing wireless devices. The wide penetration in everyday gadgets of radio technologies operating in unlicensed frequency spectrum, such ...
Low power impulse radio-ultra wide band(IR-UWB) receivers have potential application in the area of wireless sensor networks. In this paper the possibility of super-regenerative receivers for pulse detection is demonstrated. The super-regenerative receiver ...
It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...
The recent increase in the need for energy efficient wireless nodes have led to the study of various low power consumption receiver and transmitter architectures. The super-regenerative receiver architecture is one of the possible candidates for such a low ...
Recently there is an increase in interest for using super-regenerative receivers for pulse based communication systems. To receive a pulse using the super-regenerative architecture the pulse needs to be aligned with the zero crossing of the damping co-effi ...

A low-power and low-voltage super-regenerative receiver operating at 1 GHz and implemented in a 0.35-μm CMOS process is described. The receiver includes an low-noise amplifier, a super-regenerative oscillator, an envelope detector, an AGC circuitry with sa ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept avoids expensive ...

A key problem in transporting multimedia traffic across wireless networks is a controlled sharing of the wireless link by different packet streams. So far this problem has been treated as that of providing support for quality of service in time division mu ...
