I came to conclusion, together with my professor ... that the program probably ignores feedback in circuit
I am now trying to implement circuit to PSpice ..
I have a problem with the implementation of components such as transistors and operational amplifier ...
I have a library but in...
My professor wants the signal was that distorted as little as possible ...
It was nice to that sine signal was no distortion, I know that such a distortion of the transmitter was not prevent to the action ...
For me, it could have already been, because I do not have any idea how to control it...
I did like you saidwith the R8 ... but unfortunately, the amplifier is not stabilized ...
Trying to control circuit as in Push Pull Power Amplifier
**broken link removed**
but something it does not go for a frequency of 5 MHz
thank you very much for your advice ...
Now I have this problem .. I put the feedback in this way as seen in the picture ...
Unfortunately, the signal is still distorted, I do not know how I can reduce voltage, so that the signal does not try to driven as to the max ...
I try to combine the...
Hey, I did so here is layout now ... I added a high-speed operational amplifier ...
the input signal is 5 MHz sine wave 2 Vpp
problem is the slow growth of the signal up to 100 Vp
underneath the chart of simulation
I have to give up this idea ... I talked with my professor and it is not something I needed .. and it will not work very well
Now I will try to connect to one input of inverting operational amplifier, and the second non-inverting
and try to achieve something with feedback
Will be best to use a...
Hey
Recently trying to continue to make this control system
Something like the last time I tried to run
The output of this amplifier with a signal sine, 1 Vpp input gives about 7 V output
Of course, this is where the control system is not connected to the main circuit
When connected to...
Only my professor told me to do this project for the sine signal ..
When I removed the capacitors, the amplifier has stopped working
The following simulation ... what wrong plug?
something like that would be applicable in my circuit?
https://focus.ti.com/lit/ds/symlink/ucc27323.pdf
but when I plugged it in this way obviously does not work properly
And if you use an operational amplifier ...
how can I do in this circuit to the feedback?
This application will be able to act LM5104_NS_halfBridge.pdf
Only it needs a solution that I could perform in Multisim.
Your best bet would be to control the MOSFET with some of the operational amplifier with feedback.
Except that I do not know how such applications do
My project is based on...
I'm really not experienced in the design ... and this type of amplifiers is not popular.
Therefore, as you may have the schematic of such a device which could to control the amplifier ...
For now I would not worry about the loss of this amp ..
Have not checked the power losses and current...
Of course, I agree with you ... the HC49 for Xtal I just wanted to simulate the load on the output of the amplifier.
I have a problem with this mainly to somehow control this amp ... I put the following curves transient, ac analysis
I wanted to do it on an operational amplifier ... so that this...
