An Inductance-Capacitance Oscillator of Unusual Frequency Stability

An L-C oscillator having unusual frequency stability is described and briefly analyzed. The circuit is similar to the familiar Colpitts, with an L-C series circuit replacing the inductor. Such a circuit has been used as a piezoelectric oscillator, with the quartz crystal replacing the L-C series circuit, but the circuit does not seem to have been previously described as an L-C oscillator.
