A compact power-on-reset pulse generator (POR-PG) circuit with a low-power and low-voltage operation capability is presented. Proposed POR-PG was fabricated in 0:5 m 2P3M CMOS process. It was determined from simulations and measurements that proposed POR-PG works supply voltage levels between 1.8 V and 3.3 V and supply voltage rise times between 100 ns and 1 ms. POR-PG has very small silicon footprint. Layout size of proposed POR-PG circuit was 120 m Â 55 m in 0:5 m CMOS process. Comparing with other POR-PG circuits in the literature, proposed design enjoys lowest power consumption (< 6 W), smallest silicon footprint, widest supply voltage range, and additional features such as brown-out detection capability. These achieved by using a unique cascadable POR delay element that consumes very low-power.

“…In order to improve the lifespan of the monitoring systems, the project of "Near Zero Power RF and Sensor Operations (N-ZERO)" was proposed by the Defense Advanced Research Projects Agency (DARPA) in 2015 [2], which aims to develop near-zero power systems. To further reduce energy consumption, the auto-wakeup system is proposed based on various active sensors [3][4][5][6][7]. In 2017, Robert W. Reger.…”

Beaufort scale of wind force monitoring is the basic content of meteorological monitoring, which is an important means to ensure the safety of production and life by timely warning of natural disasters. As there is a limited battery life for sensors, determining how to reduce power consumption and extend system life is still an urgent problem. In this work, a near-zero power triboelectric wake-up system for autonomous Beaufort scale of wind force monitoring is proposed, in which a rotary TENG is used to convert wind energy into a stored electric energy capacitor. When the capacitor voltage accumulates to the threshold voltage of a transistor, it turns on as an electronic switch and the system wakes up. In active mode, the Beaufort scale of wind force can be judged according to the electric energy and the signal is sent out wirelessly. In standby mode, when there is no wind, the power consumption of the system is only 14 nW. When the wind scale reaches or exceeds light air, the system can switch to active mode within one second and accurately judge the Beaufort scale of wind force within 10 s. This work provided a triboelectric sensor-based wake-up system with ultralow static power consumption, which has great prospects for unattended environmental monitoring, hurricane warning, and big data acquisition.

“…In Section II, the previous works in [1] and [3] are described in detail. The second approach is to generate a POR signal until the supply voltage reaches a reference voltage that has been implemented in many cases using bandgap reference circuits [4][5][6]. However, previous approaches did not use a clock signal for implementing POR circuits.…”

Abstract-We propose a compact power-on reset circuit consisting of a switched capacitor, a capacitor, and a Schmitt trigger inverter. A switched capacitor working with a clock signal charges the capacitor. Thus, the voltage across the capacitor is increased toward the supply voltage. The circuit provides a reset pulse until the voltage across the capacitor reaches the high threshold voltage of the Schmitt trigger inverter. The proposed circuit is simple, compact, has no static power consumption, and works for a wide range of power-on rising times. Furthermore, the clock signal is available while the reset pulse is activated. The proposed circuit works for up to 6 s of power-on rising time, and occupies a 60 ´ 30 μm 2 active area.
