Hello,
Typically what sort of stability could be expected from a typical collpitts LC oscillator?
Typically what sort of stability could be expected from a typical collpitts LC oscillator?
It mostly involves the temperature coefficient of the inductor and capacitors you use.
In fact the main factor which influences the stability of a free running LC oscillator is the oscillation frequency. Lower the frequency better the stability.
I’ve seen well designed Colpitts LO’s using temperature compensated components (f = few MHz) with stability 1x10^-5
Bias currents and temperature drift of transistor parameters are also concerned..
