Hello,
Can someone please show me how to design and simulate a 4MHZ colpitts crystal oscillator, please

Hello trott1187,
You can find several schematics for oscillators like this one http://www.electronicecircuits.com/electronic-circuits/colpitts-1-to-20-mhz-crystal-oscillator online.

Hi dihidalg,
Thank you so much. I have tried to create a circuit usig the multism software.
Problems:
- When i simulate i do not see anything in the oscilloscope and spectrum analyzer.
- How do i see if the circuit oscillates at 4HMZ
I have attached the circuit, please help.

An example of 4 Mhz Colpitts using electrical equivalent to quartz crystal.

We can compare the crystal equivalent to the function generator.
Possibly the function generator will be more intuitive and less time consuming.
I think that the parameters of a given crystal circuit are more related to what we are doing.
The crystal electrical equivalent are fixed values that are inside the case of a crystal.
I believe that the crystal's drive level can be found and set. The frequency at which the crystal
likes to be will be maximum or peak on a curve. Finding tiny parameters is a real challenge.
