In this paper, an ultra-low power consumption crystal oscillator embedded in an RTC module (ASIC and its crystal resonator) is presented. The technique leverages oscillation amplitude and loads capacitance scaling; it incorporates transistor level merging ...

Harvesting energy from ambient energy sources, such as thermal gradients is one solution to address the dramatic increase in energy consumption of personal electronics. While in the field, energy abundantly available in form of heat. The use of primary cel ...

Today, the semiconductor industry is feeding our digital world with more and more data coming from compact embedded electronics that are monitoring our environment and feeding analytics for action. Interaction with our digital world is mostly achieved thro ...

Variability of Low Frequency Noise (LFN) and Random Telegraph Noise (RTN) is an important concern for many analog CMOS integrated circuits. In this paper, transistors with enclosed gate layout are examined and compared with standard layout transistors, wit ...

This work presents an ultra-low power oscillator designed to target different contexts, such as crystal-assisted time keeping, reference oscillator to optimize the always on domain of a microcontroller or wake-up timer. This oscillator enables ultra-low po ...

This paper discusses the advantages of subthreshold logic for True Random Number Generators (TRNG). In this work, the entropy is modeled, and a lower bound of Shannon's entropy per output bit can quickly be estimated. Thanks to this model, sizing TRNGs in ...
