* Question
| What is the principle of zero temperature compensation? |
* Answer
| Due to zero drift, the potentials of B and D are different. For example, when the temperature rises, the increase of R2 is relatively large, so that the potential of point D is lower than point B, and the potential difference between points B and D is zero drift..Of course, if a Resistors with a positive temperature coefficient and a large resistance value is connected in parallel on R4, the effect is the same. |
