Hello, everybody. I'm trying to construct a Colpitts oscillator circuit for 32.76 kHz. But after soldering, the circuit is not working.
What have I done:
• checked the circuit.
• checked the values to apply Barkhausen criteria (not sure about this part)
The only thing I get at the output is 5V (measuring with oscilloscope).
P.S. Maybe somebody know better working circuit to get stable 30-50 kHz oscillations (according to my needs solution should be cheap enough)
Thanks for your attention

Almost forgot to mention that I need sine (or almost sine) wave oscillations. There is a huge amount of ready made circuits for 32khz square oscillations.
