This 100 kHz oscillator was found in a 1966 Motorola publication. The transistors are of types suitable for the generated frequency and L1 / C1 depend on that frequency.
We found this circuit in an old documentation from the 70s. The text is the original one of the...
The circuit shown in figure is suggested by Maxim in an application note. The operational...
We found this amplifier in a 1990 documentation. The transistors are common, having been made...
