logic circuits, we have measured 19-stage ring oscillators. Figure 16.6.3 plots the measured stage delay as a function of varying supply voltage. At 0.5V VDD and 1V Vbias, the ring oscillator exhibits a frequency of 28kHz, with a maximum frequency of 910kHz at 10V VDD and 20V Vbias. This corresponds to stage delays of 892ns and 27ns, respectively. The ring oscillator consumes at 10V VDD and 20V Vbias, 23.82mW, and only 2.03μW at 0.5V VDD and 1V Vbias. imec, Leuven, Belgium This work demonstrates the fastest NFC transponder IC with flexible thin-film transistors (TFTs) to be implemented in flexible NFC tags which could be the missing link between the Internet-of-Things and the Internet-of-Everything. The Internet-of-Everything requires low-cost identification and sensor tags, whereby the Silicon-IC could be replaced by lower cost TFT circuits. Our roadmap focuses on thin-film transistor technologies, fabricated directly on plastic film in an
