why don't you post the specs like input signal amplitude.Well this is how far I've been working for so long.The only problem is that the imput voltage is to low to power the transitors,and I heard that I need to implement a preamplifier so that the voltage would be enough for the transitors to enter the conduction zone
Are you sure the input voltage is 1uV ( 1 micro-volt ) ? Is a frequency specified ?Hi!I have a project to do,a 12Watt audio amp.But I need a 30Kohm input resistance and 2ohm load resistance.The imput voltage being 1uV.Can you help me with an electric diagram?Thank you!
That's what I assumed when I read it. This is not a real project, just some computer exercise which is supposed to "illustrate" something.... in reality, there are no commercially available op amps which can amplify a 1uV signal with any kind of decent signal to noise ratio. The whole thing is just a waste of time.Because the profssor wanted it unusual.
Except it is 100X times as much which puts it into reality range. There are good low noise preamps like TL072 and NE5532 that can handle signal levels of 100uV with decent signal to noise ratio.It seems that I noted wrong the input voltage,it's 100uV instead of 1uV,however this is also a small voltage.
