In theory, one could also use a synthetic inductance, aka 'gyrator". I
took a gyrator based audio oscillator that used 741's and on LTSpice
rebuilt it using 1000 Mhz GBW op-amps. Using an FFT of a transient
analysis I had a nice narrow adjustable center frequency peak of about
10 Mhz, But I never did have a chance to wire it up, as I have a baby
to take care of.
