A 0° Phase Shift Oscillator that works with voltages as low as the voltage drop of the bjt transistors being used, (so 0.7v for Silicone as in this example).
This circuit uses two LC filters tuned to resonate at 50MHz; the oscillations can get really close to the resonant frequency, but it’s not exact, it’s about 6.35% lower in this example.
