Hi, my name is Quan and I am new to this forum. I am trying to build a discrete operational amplifier but I am very weak with circuit designing since my concentration is in communication. Anybody here have a lot of experience building analog op-amp circuits? If you are in the area then that's great but I am sure we can still work together through the internet otherwise.(adsbygoogle = window.adsbygoogle || []).push({});

The spec for the design is as follow:

Two inputs: 1 plus and 1 negative

Discrete devices (BJT, FET, TUBES) only

Gain between 1000 – 1500 to provide a maximum +/10 output signal

Frequency response DC – 10 Mhz +/- 2db

Has to be able to drive a 50k load

Input impedance of at least 1 Megohm

Output impedance less than 50 ohms

Temperature range: 25 – 100 degrees Celcius

Please e-mail me at quan24@gmail.com if you can help. Thank you in advance!
