    Hi folks,

    I am working on a design where I would like to implement the following transfer function...

    Vout = 1.3^(Vin)

    I have read up on the exponential amplifier section of this page and I understand how the theory of how the exponential amplifiers work. I have done some web searches related to exponential amplifier and I found that the base of the exponential function is based (pun emphasized) on the saturation current of the diode (or transistor).

    Has anyone built an exponential amp before? If so, can you please share some tips in regards to setting the value of the base? I would really appreciate it if you can help.

    Sincerely,
    -Scott
