Abstract-Development of a low-power, small-size transmitter is needed for wireless sensor networks.An effective way to reduce power consumption is to reduce the operating time in a voltage-controlled oscillator. In this study, a 2.4 GHz on-off keying (OOK) transmitter circuit is designed and implemented with an electrically small antenna using a left-handed transmission line. The transmitter circuit was fabricated with a standard 0.18 µm CMOS technology, while the antenna was fabricated with a 3.0×4.5 cm printed circuit board, chip capacitors, and chip inductors. Measured output power was -6.8 dBm with a power consumption of 3.59 mW when the baseband signal was always "high". The power consumption was reduced to 1.96 mW for the baseband signal with a mark ratio of 0.5.

In power-limited wireless devices such as wireless sensor networks, wearable components, and Internet of Things devices energy efficiency is a critical concern. These devices are usually battery operated and have a radio transceiver that is typically their most power-hungry block. Wake-up radio schemes can be used to achieve a reasonable balance among energy consumption, range, data receiving capabilities and response time. In this paper, a high-sensitivity low power wake-up radio receiver (WUR) for wireless sensor networks is presented. The wake-up radio is comprised of a fully passive differential RF-to-DC converter that rectifies the incident RF signal, a low-power comparator and an ultra low power microcontroller to detects the envelope of the on-off keying (OOK) wake-up data used as address. We designed and implemented a novel low power tunable wake up radio with addressing capability, a minimal power consumption of only 196nW and a maximum sensitivity of -55dBm and minimal wake up time of 130μs without addressing and around 1,6ms with 2byte addressing at 10Kbit/s data rate. The flexibility of the solution makes the wake up radio suitable for both power constrained low range application (such as Body Area Network) or applications with long range needs. The wake up radio can work also at different frequencies and the addressing capability directly on board helps reduce false positives. Experimental on field results demonstrate the low power of the solution, the high sensitivity and the functionality.

We present an ultra-low power 60-GHz band wakeup receiver (WuRx) designed and fabricated with a 0.18-m RF CMOS low-cost technology. The WuRx consists of an envelope detector, high-gain baseband amplifier, and clock and data recovery (CDR) circuit. Subthreshold-operated offset-voltage cancellers are used in the detector and baseband amplifier. The envelope detector can operate for an on-off keying (OOK) signal with a low bit-rate baseband and 60-GHz carrier, which is higher than the cutoff frequency (f T ) of 0.18-m MOSFETs. This is because the f T defines the maximum operating bit-rate of the baseband signal. The CDR circuit is composed of a clock recovery circuit using an injection-locked oscillator, short pulse generator, and D-type flip/flop. The fabricated WuRx successfully operates with power consumption of only 9 W from a 1.5-V supply and a high sensitivity of -68 dBm for a 350-kbit/s OOK signal with a 60-GHz carrier. The CMOS die area is 1.09 mm 2 . This is the first successful fabrication of a 60-GHz WuRx.
