Temperature Sensor Electronic Components

1. Importance of Temperature Sensors in Various Applications

Temperature sensors play an important role in many applications. For example, maintaining a specific temperature is critical for equipment used to make medical drugs, heat liquids, or clean other equipment. For such applications, the responsiveness and accuracy of the detection circuit is critical for quality control. 

2. Challenges in Developing Efficient Temperature Sensing Circuits

More frequently, however, temperature detection is part of preventive reliability. For example, while a piece of equipment may not actually be performing any high-temperature activity, the system itself may be at risk of overheating. This risk is caused by specific external factors (such as harsh operating environment) or internal factors (such as self-heating of electronic equipment). By detecting when overheating occurs, the system can take preventive action. In these cases, the temperature sensing circuit must be reliable over the expected operating temperature range of the application. For decades, the need for increased performance in integrated circuits has been met by radical scaling of transistor size and increased chip complexity. In these ways, the supply voltage and capacitance of the device can be reduced by shrinking the size of the device. However, small geometric effects play a major role in the degradation of integrated circuit performance levels. These effects lead to an increase in leakage current, which leads to an increase in static power consumption, and the power consumption of the integrated circuit and the corresponding die temperature are also continuously increased.
