EnglishIn this paper, two circuit topologies of pW-power Hz-range wake-up oscillators for sensor node applications are presented. The proposed circuits are based on standard cells utilizing the Dynamic Leakage Suppression logic style [4]-[5]. The proposed oscillators exhibit low supply voltage sensitivity over a wide supply voltage range, from nominal voltage down to the deep sub-threshold region (i.e., 0.3V). This enables direct powering from energy harvesters or batteries through their whole discharge cycle, suppressing the need for voltage regulation. Post-layout time-domain simulations of the proposed oscillators in 180nm show a power consumption of 1.4-1.7pW, a supply-sensitivity of 55-40%/V over the 0.3V-1.8V supply voltage range, and a compact area down to 1,500μm2. The very low power consumption makes the proposed circuits very well suited for energy-harvested systems-on-chip for Internet of Things applications.
