We are looking to get a designed layout with calculations of an operational amplifier that will satisfy the following capabilities: A. Have two inputs possitive and negative. B. Will drive a 50Kohm load to +10V C. Will have frequancy responce 10Mhz +2db D. Input impedance 1Mohm. Output impedance 50ohm E. Can use only BJT's or FET's (discrete devices) F. Gain must be between 1000 to 1500 Also we would like you to build the physical board (it must be hand made soldered on a board) and tested to work for the given specifications. We need this to be shipped to US after completion. The shipping will be paid separately.

Hello, I'm very interested to do this project and also have the experience to do it precisely according to the specifications. A few clarifications , 1. Are you looking to build an op-amp using Bjt or just design an existing op-amp to meet your requirements? 2. Drive output to 10v. Is this AC swing? If so, what is your input voltage? 3. Frequency. Do you mean 2db gain at the specified frequency? 4. Input and output impedance depend largely upon the mode of operation. inverting, non-inverting, differential, etc. So.... please contact me with all these details so that I can design it properly. I am willing to do the design on a perforated board. Hand soldered. Thank you. Regards, Nida Subhani
