Oscillator in Multisim and EasyEDA

2263 4

Hello friends of EasyEDA. I have a problem. I made an oscillator in the Multisim program and it generates a sine wave and then I made the same oscillator circuit in EasyEDA and it does not generate any wave. What happens? Why does not it generate any wave? ![Colpitts Oscillator 49 mhz.jpg](//image.easyeda.com/pullimage/d0vBX8wqEnc3XYP6LVHaZIdPTVDEjAzx3qXAeoFH.jpeg) ![Colpitts EasyEDA.jpg](//image.easyeda.com/pullimage/GBwh62KwZQXSoVj6cxBb53HTnIx52rP0O4QUQp7t.jpeg) ![Onda de Colpitts EasyEDA.jpg](//image.easyeda.com/pullimage/lu8plmJKRCRRBXoBt17wXsZN19ltnWz6eeSTdj4d.jpeg)

Might not be the case as I don't use EasyEDA simulator, but sinewave oscillators often rely on a bit of noise injection to get them started. Try shorting L1 to Gnd then letting go again.

Mr MikeDB and friends of EasyEDA I modified the oscillator circuit but this circuit does not generate any sine wave. Next I show you the schemes. I want the circuit to oscillate but none of the two oscillators that I show can oscillate. I accept suggestions. ![Oscillator of 49 mhz.jpg](//image.easyeda.com/pullimage/lTVCxkcduRt88jE9Ja2KcURxI0tSvNw9I0eEZprX.jpeg) ![Grafica de oscilador.jpg](//image.easyeda.com/pullimage/XJ2nGlZ4buWTzTS4Qz7YJi8QWMwi9JUzQidgoE1Y.jpeg)

Do you have any oscillator circuit that generates a sine wave between 30 and 100 mhz that has been tested in the EasyEDA simulator?
