Tradeoffs: MEMS vs. Crystal Oscillators Figures 1a and 1b show block diagrams of a MEMS oscillator and a crystal oscillator circuit. The MEMS oscillator is more complicated.

1. The fundamental resonant mode of a quartz crystal can be modeled as an LCR network shunted by a capacitor. For crystals operating in the fundamental mode with a 5-MHz to 30-MHz frequency range ...

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 ...

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 ...

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 freque… ...

A finite state machine (FSM) controls capacitance, and is only clocked when the oscillator is strong enough to feed it – decided by an amplitude detector and a digital circuit which “ensures that ...
