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 ...
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 ...
After years of intensive research effort, the design of RF integrated circuits in CMOS has now reached a wide acceptance for industrial designs. This is due to the high unity gain frequency and low-noise performance of today's deep sub micrometer MOS trans ...
Recently, sequential Monte Carlo methods have been used in the telecommunications field, finding application in receiver design. Several properties of these receivers make their designs very attractive. These receivers do not require channel state informat ...
A design technique for implementing a low-voltage and low-power quadrature oscillator operating at radio frequencies is proposed. The oscillator utilises a cascade of four stages of capacitive-source amplifiers to generate balanced quadrature signals. The ...
A method and apparatus for a fast and automatic setting of the phase locked loop (PLL) output frequency that significantly improves linearity, locking range as well as spectrum purity, jitter and phase noise performances is disclosed. I n one embodiment, a ...
In recent years, optical gas detectors based on a tunable diode laser absorption spectrometer has become more and more important for monitoring trace gases in atmospheric, medical, and industrial processes. In the medical field, blood gases, essentially pO ...
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 ...
The recent advances made in MEMS and particularly in RF MEMS technology are enabling new architectures for the integration of RF transceivers with improved performance and smaller size. Several fundamental building blocks benefit from the availability of h ...
The transceivers of a wireless sensor network (WSN) have to fulfill the low-power and low-voltage constraints. The WiseNET project has already proven that it is possible to design a receiver working at 1V and consuming less than 2mW. However this transceiv ...
