N2 - Self-powered clocks and time-keeping devices pro-videan ability to synchronize events across passive internet-of-things and tags that are spatially separated from each other. Inthis regard, Fowler-Nordheim tunneling based self-powered timers havebeen shown to reliably track timewithan operating life-cycle greater than 2 years. However,the synchronization accuracy ofasingle FN-timer is determined bythe variations in timer-device artifacts whichcouIdonlybe partially mitigated using ensemble averaging. Inthis paper, we propose anovel capacitively coupled network of FN-tunneling timers that can significantly improve the accuracy in presence of both timer-device and coupling capacitor mismatch. Using Monte-carlo simulations, weshow that by choosing an appropriate sizeof the coupled network, the synchronization accuracy ofthetime-keeping devicecanbe increased bya factor of20dB.
