Appreciate the warning, but opur systems detect nothing. What software do you use? Some can give false positives.

Surely for a university project you should be designing something yourself, not copying from a schematic. Even if you just make a basic low frequency amp yourself, that would be good if you explain how it worked and why you had to do it like that.

Antivir, but well known among many other scan engines.

Hi, Umut

I am from GYTE department of Chemistry. Although my profession is PhD in Chemistry I am interested with electronics as hobby. Any way, Workbench is not a good simulation program and it always fails( not doing the simulations correctly). If you would like to simulate some switching circuits , i suggest you to free linear's LT spice. You can simulate Philips' UCD or RX-5's versions in LT spice. I do not know, if LT spice has drivers or others in it. What kind of driver you would like to use? IR2110,2113,2104,2105 or other drivers supplied from other manufacturers like intersil HIP4080,4081,2111 etc. I suggest you to use intersil's HIP series. They also have a class-d amp eval board with shematic. I have some shematics also. If you want please contact me.

Regards
Ferda
