P-3: Hybrid-Type Temperature Sensor using Thin-Film Transistors

We have developed a hybrid‐type temperature sensor using TFTs. We combined a transistor, capacitor, and ring oscillator and detected the temperature by measuring the oscillation frequency. The large temperature dependences of the off‐leakage currents can be utilized, and simultaneously only a digita...

Zusammenfassung:We have developed a hybrid‐type temperature sensor using TFTs. We combined a transistor, capacitor, and ring oscillator and detected the temperature by measuring the oscillation frequency. The large temperature dependences of the off‐leakage currents can be utilized, and simultaneously only a digital circuit is required to count the digital pulse.
