Sawtooth waveform by simple BJTs, but dips at the top.
|
Hi, :
?
I have uploaded the file named '20250318_bootstrap time-based triangle-wave generator for frequency sweep.asc' at temp.
?
The idea is to generate a sawtooth waveform for jittering in PWM.
?
But at the top peak, Vout dips, it shows flaw of discontinuity. The image showing the phenomenon.
?
If you could share some opinions to fix it, I much appreciate you very well.
?
Wish you all happy & healthy.
?
Best regards.
