What about it? You want to start with an oscillator that is very temperature sensitive and fix it. Why? Why not start with a less temperature-sensitive oscillator?what about my oscillator ??
Huh? Why does that make you NOT want to start with a good, stable, temperature-compensated oscillator to begin with?because my sensor is sensitive to conductance and the effect of condcutance decrease at 100 MHZ
i must use a temperature sensor to compensate temperatureWhat you need is a crystal oscillator oven or a temperature controlled crystal oscillator:

Do you not see the oxymoron? If you need to apply compensation, then it is NOT a good choice for temperature stability. You need a temperature-stable oscillator, right? There is such a thing and it's not your Clapp oscillator.i'm working with Clapp oscillator which was chosen for its temperature stability but thermal compensation circuit must be added to compensate temperature change in soil
So are you claiming that a Clapp oscillator is more temperature stable than an oven-controlled crystal oscillator? If not, then why did you not choose it instead?i'm working with Clapp oscillator which was chosen for its temperature stability but thermal compensation circuit must be added to compensate temperature change in soil
