“…All of the concepts fulfill [23,30,51] fulfill the requirements, for the industrial only one [51]. A duty-cycled nRF51822 with a data rate of one or two Mb/s also meets the industrial requirements, but only with a sensitivity worse than the concept in [51].…”

“…The concept presented by Le-Huy et al [50] uses binary Pulse-Width-Modulation (PWM), while the concept by Marinkovic et al [28] uses a multi-stage approach beginning with an OOK modulated signal followed by a PWM symbol. The other concepts use Phase-Shift-Keying (PSK); Yan et al [57] use the binary form BPSK and Lee et al [51] use the quaternary form Quadrature-Phase-Shift-Keying (QPSK), which could also be implemented as two parallel BPSK demodulators.…”

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 die area is ~6 × 1.6 mm 2 . The low voltage IC realizes the wireless transceiver that communicates with the external master control unit (MCU) as discussed in [9]. The communication system utilizes a QPSK modulation scheme and can communicate on one of 4 different channels to avoid interference.…”

The IC designs of an implantable functional electrical stimulation (FES) battery-powered micro-stimulator are presented in this paper. The battery is recharged by receiving power magnetically through a coil under supervision of a power management unit. To limit the heat generation on the stimulator when a large magnetic field is present, an on-chip rectifier is capable of reducing the Q factor of the coil using a time-varying method. The same coil is also used for generating and receiving magnetic fields such that the distances among 16 different stimulator pairs can be estimated simultaneously. The stimulation current is produced from an 8-bit exponential DAC that has a range between ~2.5µA and ~10mA. The stimulator communicates with an external master control unit through a 400MHz wireless link that can support a bit rate of ~2.5MB/s in high speed mode. The total number of stimulators that the communication system can support is 852. IEEE 2008 Custom Intergrated Circuits Conference (CICC)978-1-4244-2018-6/08/$25.00 ©2008 IEEE 13-1-1
