The basic requirements for crystal oscillator circuit design are the same no matter what circuit is used for the active element. In order that the oscillator may start when power is supplied to the circuit, and that it may deliver the required power to the load, the correct impedance, phase...
A quartz crystal provides a large Q tuned circuit that affords the end oscillator high-frequency stability. As stated previously, this was not a problem when there was only one designer and vendor involved in the oscillator design, but now you have the crystal vendor, semiconductor manufacturer,...
Oscillator Circuit Design: When the crystal is attached, an oscillator circuit must be created to provide a steady frequency signal depending on the crystal’s resonance frequency. A feedback loop is often part of the oscillator circuit and uses the crystal to maintain the output signal’s freque...
An oscillator is an electronic circuit which generates a repetitive signal. This signal can be in many forms depending on the application
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide ...

Crystal Considerations with Da-Abstract: This application note describes crystal selection and layout techniques for connecting a 32,768Hz crystal to a real-time clock (RTC). It also provides information about oscillator circuit-design criteria, system d
A known crystal oscillator circuit is modified to improve the starting of oscillations therein when a low supply voltage is employed. The oscillator circuit includes two complementary field effect transistors connected in a known manner to each other and a frequency determining circuit including a cryst...
