How much power does a wake-up timer use?
Our timer generates mean wake-up frequency of 0.24 ± 0.15 Hz, with a mean power consumption of 26.7 ± 14.1 nW. In this paper, we provide details of the Wake-Up timer’s design and performance at different supply voltages, under temperature variations and different light conditions.
How does a wake-up timer work?
The Wake-Up timer stabilizes completely after the hour mark. At roughly the 90-minute mark, a LED lamp engages 30k lux directly onto the chip and instantly a frequency drift is noticeable. Different chips present slightly different frequency variation patterns. b Output frequency response of the WUT to an on/off light test.
How does an ultra-low power timer reduce system power consumption?
Here, we present an ultra-low power timer designed to wake-up an external circuit periodically, from a deep-sleep state into an active state, thereby largely reducing the system power consumption. We achieved this with a circuit topology that exploits the transistor’s leakage current to generate a low frequency wake-up signal.
How can a transistor generate a low frequency wake-up signal?
We achieved this with a circuit topology that exploits the transistor’s leakage current to generate a low frequency wake-up signal. This topology is compatible with IC technologies where only n-type transistors are available.
What is a flexic wake-up frequency (Wut)?
To the best of our knowledge, this is the first report of a WUT specifically designed for FlexIC technologies. The circuit generates mean wake-up frequency of 0.24 ± 0.15 Hz, which is an ideal value to monitor periodically human-centered activities. At the same time, mean power consumption is as low as 26.7 ± 14.1 nW.
