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 ...

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

Starting a crystal oscillator fast in an IoT node is an art: the high Q needed for stability means they take milliseconds to get going, just to transmit a 128μs Bluetooth LE packet, and power is at a ...

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 ...

Crystal oscillators are incredibly useful components, but they come with one little snag: their oscillation is temperature-dependent. For many applications the relatively small deviation is not a ...
