Not yet.Did you measure the oscillator frequency?
Not yet.Did you measure the oscillator frequency?
I asked because i calculared 88kHz and so there may be gain bandwidth issues for the op amps.Not yet.
I will try to measure the frequency.
Hopefully, by selecting the circuit modes, it will be possible to get a frequency of 80-100 kHz.
Regarding the operational amplifier, then the choice is not great. So far I have only TL062,072.
C1 probably OK if you want 100kHz. Adjust R4 for frequency.Hi,
Thanks.
The situation is more or less clear.
What do you think about the capacitors C1, C2, C3?
C1 ceramic.C1.Any type of capacitor can apply?
In this case, can it be better to use instead of electrolytic capacitors C2, C3 ceramic capacitors with low ESR?
In addition to the ceramic capacitor, can I use a different type? Polypropylene or polystyrene? Does the quality of this capacitor have any meaning?C1 ceramic.
Ceramic should be fine.In addition to the ceramic capacitor, can I use a different type? Polypropylene or polystyrene? Does the quality of this capacitor have any meaning?
I will show one.
His capacitance is different, but this is just for example. In my opinion, very high-quality capacitors.
Is this still the circuit?Transformer used ready from the old monitor.
R5, R6-1Ohm.
We actually have a fairly good range of 0.02-20 Ohm.
What scheme? I already posted one way back in this thread.Yes. I have already said that I will do the original circuit with a transformer.
And I will do your circuit later, because I do not have the necessary operational amplifiers.
Are you going to make your scheme or not?
Yes, indeed it is better.It's really better to post an image for a circuit if that is all that is being posted.
