Noise effects on 'thermal diode' systems

Posted: 12 Sep 2008     Print Version  Bookmark and Share

Keywords:thermal diodes  thermistor  noise coupling 

This is the last in a series of three articles on thermal diodes. The previous two articles of the series demonstrated how 'thermal diodes' are used to measure temperature and developed an understanding of the internal variables of 'thermal diodes' used in temperature measurement systems.

Unlike the two previous articles, this article addresses an external variable—noise coupling. It discusses the effects of noise coupling on 'thermal diode' systems and methods to prevent it.

It also explains the methods used to detect temperature using a thermistor and a thermal diode. It explains how the voltage is measured for a specific forced current and shows equations on about how I-V responses differ in using a thermistor as opposed to using a thermal diode.
