A very simple DIY crystal oscillator circuit which use a quartz for frequency stability and a good rf transistor. Use a 2-nd or 3-rd harmonic crystal, for example if you want 100MHz use a 50MHz or ...

[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies and since ...

Primary design considerations for fundamental-mode oscillators using AT-cut crystals include load capacitance, negative resistance, startup time, frequency stability versus temperature, drive-level ...

Crystal oscillators are fundamental components in modern electronic systems, providing the precise timing necessary for communication, computation, and sensor network operations. Recent advances in ...

Another great crystal oscillator circuit with BB139, a 2-nd harmonic quartz crystal and one BF214 transistor. So, the Q quartz is half of the desired transmitter frequency, L1 has 24 turns, 0.08mm Ø ...
