“…The ambient RF radiation with a power density of several nW/cm 2 opens up applications of sustainable batteryless wireless sensor nodes with minimal functional capabilities. These batteryless wireless sensor nodes can be deployed in harsh and remote environments for sensing and monitoring applications [81]. The batteryless operation improves the sustainability of the sensor nodes, ensuring zero battery replacement and low maintenance costs.…”

“…∂ V CTAT /∂ T as shown in ( 14) and ( 16) has a typical-negative value, and it depends on the technology parameters α and V BE . ∂ V CTAT /∂ T can be modified by adjusting the current I C dependent term V BE (see (1)). The second-order term ∂ 2 V CTAT /∂ T 2 ≈ −4 μV/K 2 depends on the absolute value of V BE (see (15) and ( 16)).…”

“…U LTRA-LOW-POWER solutions are required in order to sustain the ever-increasing demand for wireless sensor nodes. The vast network of battery-operated low-power wireless sensor nodes is constrained by the battery usage [1], [2], [3]. The battery usage can be reduced by a radiofrequency (RF) powered wake-up receiver (WuRx).…”

This paper presents a curvature-compensated sub-1V voltage reference (VR) and a shared-resistive nanoampere current reference (CR) in a 130 nm CMOS process. The CR is used to generate a bipolar junction transistor complementaryto-absolute-temperature voltage, which is summed up with a proportional-to-absolute-temperature voltage generated using a summing network of PMOS gate-coupled pairs. The measured output voltage and current references from 10 chips (V REF and I REF ) at room temperature are 469 mV and 1.86 nA, respectively. The measured average temperature coefficient of V REF and I REF are 29 ppm/ • C and 822 ppm/ • C over a temperature range from −40 • C to 120 • C. The minimum supply voltage of the voltage-current reference is 0.95 V, and the total power consumption is 30 nW.

“…Industry surveys show that batteries are the bottleneck for scaling IoT devices due to their limited lifetime and replacement costs [1], [2]. For IoT devices mostly in idle mode, the battery life can be extended by including a wake-up receiver (WuRX) which keeps the node in sleep mode unless woken up [3].…”

This brief presents a fully passive RF wake-up receiver (WuRX) fabricated in a 130 nm CMOS process with a matched small loop antenna. The WuRX consists of a high-sensitivity RF energy harvester that supplies the circuitry necessary for passive WuRX functionality. The circuit consists of an on-chip voltage reference, current reference, power-on reset, low-dropout regulator, relaxation oscillator, envelope detector, comparator, and a digital processor. The WuRX supports an input bitrate of 26 kbps and has a user-defined 12-bit wake-up pattern. Measurements at 830 MHz reveal a wake-up sensitivity of -30.7 dBm and a 1 V harvested output sensitivity of -31 dBm. The RF-powered fully-passive WuRX paves the way for autonomous batteryless sensor nodes.
