In wireless sensor networks (Wsns) energy efficiency and communication reliability are often conflicting requirements. additionally, some application areas such as industrial automation or infrastructure monitoring impose strict latency bounds.Low-power receivers ( mW 1 1 power consumption) together with adapted mac protocols have the potential to meet these diverse requirements. We present an overview of state-of-the-art low-power receivers and relate their characteristics to requirements for different application areas. We compare low-power receivers to duty-cycled transceivers and present applications depending on them. For this, we use power consumption, sensitivity, and data rate as key performance figures for low-power receivers. Based on the characteristics of the applications we derive guidelines for using low-power receivers instead of duty-cycled transceivers. project "AETERNITAS".Johannes Blanckenstein works on communication protocols in the general field of wireless sensor networks and especially on protocols and applications for low-power wake-up receivers. He writes his doctoral thesis at University Paderborn in the computer networks group of Holger Karl. At the same time he works at Airbus Group Innovations in the field of WSN applications for aeronautics.

“…The simulated common-mode suppression from 0.5 to 2.5GHz (the intended band of operation, since the 2-10GHz IF input is divided by 4 by the ILO) varies from 40-50dB at either port. The mixer conversion gain is limited by the output impedance of tail current sources M 7,8,9 , and a 75Ω degeneration resistance is employed at each source node to increase their output impedances. The injection-locked stage provides rail-to-rail swing that allows the mixer to be designed for low power consumption.…”

An FM demodulator operating across 8GHz IF bandwidth for application in low-power, wideband heterodyne receivers is presented. A 4-stage ring oscillator is frequency modulated by a wideband input. Locking to 1/4 th the input frequency, it divides the FM deviation by four, thereby reducing the energy required for wideband demodulation to 0.75nJ/bit. Autocorrelation of the quadrature-phased outputs using a new low-power folded CMOS mixer is capable of detecting FM up to 400Mb/s over 2-10GHz IF. The inductorless 65nm CMOS prototype circuit occupies 0.17mm 2 and dissipates 3mW from 1.2V.

“…ITC uses a diode-connected threshold voltage generator to generate a gate bias voltage from a rectifier's output dc voltage. In [15]- [18], a self-bias approach used in a singleand multiple-stage rectifier is proposed. This technique utilizes the internal dc voltages between each stage to bias the gates of the rectifying transistors in adjacent stages.…”

This paper introduces a new class of RF-to-dc rectifiers called the in-phase gate-boosting rectifier (IGR). An IGR utilizes an in-phase passive voltage multiplier (IPVM) to boost in-phase swing from the driving swing. This design simultaneously reduces the effective threshold voltage, forward resistance, and the reverse leakage current of the rectifying transistor. As a consequence, the sensitivity and the efficiency of a high-frequency rectifier can be improved. Furthermore, a -loaded IPVM presents low input conductance and is shunted with the drains/sources of the rectifying transistors. This makes the realization of the input matching network between the IGR core and the antenna easier, and achieves a higher voltage swing at the input terminals of the IGR core. The criteria, properties, and relating proofs of the IPVM are also discussed. A differential seven-stage millimeter-wave IGR is implemented in a 65-nm RF CMOS process. In this design, an interleaving internal threshold cancellation bias scheme is also introduced to further suppress the power consumption due to biasing circuitry without increasing the layout area. The implemented integrated circuit achieves a state-of-the-art 7-dBm sensitivity with 20% peak efficiency at 53 GHz and a bandwidth of 10 GHz from 46 to 56 GHz.
