“…This section briefs how aging affects the oscillation frequency of RO and its mitigation. As discussed in [45], out of different sources of aging like NBTI (negative bias temperature instability) and HCI (hot carrier injection), NBTI is the primary cause of degradation in the oscillation frequency of RO. The degradation in f ossc of RO due to NBTI occurs even if the RO is in an idle state.…”

Recently, harvesting natural energy is gaining more attention than other conventional approaches for sustainable Internet-of-Things (IoT). System on chip (SoC) power requirement for the IoT and generating higher voltages on-chip is a massive challenge for on-chip peripherals and systems. Many sensors are employed in smart cities and smart villages in decision-making, whose power requirement is an issue, and it must be uninterrupted. Previously, we presented Security-by-Design (SbD) principle to bring energy dissipation and cybersecurity together through our "Eternal-Thing". In this paper, an on-chip reliable energy harvesting system (EHS) is designed for IoT end node devices which is called "Eternal-Thing 2.0". The management section monitors the process load and also the recharging of the battery/super-capacitor. An efficient maximum power point tracking (MPPT) algorithm is used to avoid quiescent power consumption. The reliability of the proposed EHS is improved by using an aging tolerant ring oscillator. The proposed EHS is intended and simulated in CMOS 90nm technology. The output voltage is within the vary of 3-3.55V with an input of 1-1.5V. The EHS consumes 22µW of power, that satisfies the ultra-low-power necessities of IoT sensible nodes.

“…Since the introduction of the ring oscillator implementation on FPGAs by Boemo and Lopez-Buedo [13], there has been various reports on new applications and techniques to utilise the ring oscillators as thermal sensors [14][15][16][17][18]. The clear advantages of ring oscillator implementation are hot spot detection, signal contentions and flexibility in supporting multiple input sensors for thermal measurement of the FPGA [19,20]. The ring oscillator is chosen due to its near-linear dependence of logic delay on temperature [17,21].…”

Thermal issues are rapidly evolving in the field-programmable gate arrays (FPGAs) and are being intensely studied as these issues appear to significantly affect the delay performance of FGPAs. A ring oscillator has been widely used as a digital temperature sensor to sense this thermal effect on FPGAs. The delay generated by the ring oscillator will vary depending on the temperature environment due to negative bias temperature instability, hot carrier injection and electromigration. It is therefore critical to adopt an accurate ring oscillator design to effectively measure the delay in FGPAs. In this study, a digital temperature sensor with a stable ring oscillator is proposed. Measurement periods of 512 and 4096 clock cycles have been implemented and the relationship between temperature, delay and total count has been established. The results show that as the temperature increases to 100°C, the delay decreases by 3.99 and 33.98% for 512 and 4096 clock cycles, respectively. It has been found that in order to reduce the degradation effect on the Virtex-6 FPGA, adopting a measurement period of 512 clock cycles is the best method. The measured data is successfully validated through a set of simulations. Thus, it may benefit a system designer and industrial player, especially in designing temperature-based FPGAs.
