Hmm, would a single RC low pass for 10MHz suffice? I suppose i will also have to use a unity gain VCVS as buffer too. I'll try to build it when i get home.
I thought that disabling could be different from skipping, but i always try both ways nonetheless, i'm adventurous hehe.
Here's my latest results:
Changed the circuit, switched ideal op amp for a 741, it will be just fine for a 10kHz oscilation.
I could not produce a stable, perfect...
Yes, i changed my values to try to reproduce Brad's 10kHz wave. I'll have a go with your setups and will return with the results. Oh, and by disabling initial bias point calculation do you mean to leave that box unchecked? If i do so my output wave is zero. Thank you.
I ditched Proteus because...
Oops, didn't notice the bandwidth, huge mistake. Anyways, i switched the lm741 for an generic ampop, changed my capacitor values to match Brad's and corrected the gain feedback loop, the 100k resistor was shorted with the inductor. Here are the results, the smaler window is a 100m cycle zoomed...
Hello,
I'm trying to simulate a 10MHz Colpitts Oscillator using an OPAMP, but i'm not getting the expected outcome, the frequency is not 10MHz and the output amplitude is very low. I've read somewhere that Proteus doesn't simulate the natural noises necessary to satart the oscillator, so i'm...
