Is feedback required for oscillation in an "LC oscillator" ?

    As clear from the subject I want to know whether any kind of feedback
    is required for oscillation in an LC oscillator??

    Yes, sort-of.
    One must have sufficient *gain* in order to (more than) overcome the
    losses, AND one must take that amplified output and feed it back so that
    the *phase* (at least at the frequency of interest) is the same as the
    original un-amplified signal.
    So just having feedback is not sufficent, but it is necessary.

    Necessary, but not sufficent; gotta spec the gain and gotta spec the

    I think, since the oscillators are named after their designers, they
    are more stable in their configurations.
