Temperature compensation trim method |
摘要 |
The present invention overcomes the disadvantages of the prior art and provides a new temperature compensation trimming technique. Temperature compensated output is provided in a logarithmic voltage output device by the steps of: measuring the resistance of a first resistor, a second resistor, and a third resistor at a first temperature; measuring again the resistances of the first resistor, second resistor, and third resistor at a second temperature; and trimming the drift of the third resistor according to a calculated temperature compensation trim.
