Quartz Crystal Oscillator

This quartz crystal oscillator circuit has greater stability than a parallel resonance circuit. It generates frequencies up to 30 MHz or even higher if you use BFR91 for T1, T2 transistors and reduce R1 … R2 values. The MOSFET buffer insulate the oscillator from any connected circuit.
