i utilized ckt on bread board and measured on dso …the output experienced only 800mv ac element of 40mhz whilst other section was dc element of about 4v . i used Vcc of 5v . what I would like is atleast 4v peak to peak and also 9v peak to peak if Vcc is 9V …watching for rapid reply
The Q issue, that is a evaluate of the caliber of resonance circuit of a crystal, may be very substantial. The Q aspect of the crystal may possibly range from 104 to 106 Whilst the L-C circuit might have a Q factor only with the purchase of a hundred.
As time passes, the frequency of the crystal oscillator might drift on account of aging from the quartz crystal. Even so, this drift is often very tiny and might be minimized by deciding upon higher-top quality crystals.

This circuit was well known right until the nineteen forties. They are extensively Utilized in the regenerative radio receivers. In that input, the radio frequency sign through the antenna is coupled magnetically in the tank circuit as a result of an additional winding, and feedback is decreased to achieve Handle while in the opinions loop.
The crystal oscillator circuit commonly operates on the basic principle in the inverse piezoelectric outcome. The utilized electric industry will generate a mechanical deformation across some elements.
A mechanically vibrating crystal is often represented by an equivalent electrical circuit consisting of lower resistance R, a large inductance L and modest capacitance C as shown under.
Just activate the AM radio and modify the dial to a band that is definitely on the low-frequency Component of the spectrum.
Normally, the utmost running frequency relies upon on the switching characteristics from the logic gate utilised.
Vulnerable to Shock and Vibration: Crystal oscillators are sensitive to shock and vibration, This will influence their precision and security.

This technological innovation ensures that the OCXO operates in a crystal's turning place, in which the frequency vs. temperature curve's slope is zero.
On this configuration, it can be connected in between the collector and foundation of the transistor amplifier stage to supply responses at the resonator's specified get more info frequency.
