Hybrid-type Temperature Sensor using Thin-Film Transistors generating Rectangle Output Waveform - Operating Confirmation by Actual Experiment

We have developed a hybrid-type temperature sensor using thin-film transistors generating rectangle output waveform. The advantages of the hybrid-type temperature sensor are that the large temperature dependence of the off-leakage current can be utilized, and simultaneously only a digital circuit is required to count the digital pulse. However, the conventional hybrid-type sensor has a disadvantage that the pulse width is too small to count. Therefore, we have developed a new hybrid-type temperature sensor in order to enlarge the pulse width. Although we previously confirmed the operation by circuit simulation, particularly in this presentation, we have made an actual circuit and observed a rectangle output waveform, namely, confirmed the correct operation by actual experiment..
