Found in a 1970 American publication, this circuit uses transistors of the time. These transistors may be replaced by current equivalents. The factor Q is greater than 3 000.
I found this circuit in an old document from 1981. The circuit can be implemented today with the...
The circuit presented is a 10 MHz oscillator with crystal, which already has several splitters for...
