Hello everyone, I have a problem with a 40kHz oscillator that I am building with a crystal. My problem is the stability of the signal.
Because although the frequency and amplitude is correct, the signal is unable to maintain a zero or reference line, as this all the time jumping all the signal from positive to negative.
If anyone knows how I could fix this I'll be very grateful. defase since this signal, I also moved to the driver of ultrasound transducers.
regards
and thanks!
