    I need to design a transistor based feedback current amplifier to provide the maximum possible gain Af using at most three MOSFET transistors. The supply voltage is 3.5V and maximum allowed total supply current is 1mA. The signal current source has a source resistance of Rs=1kΩ and the load is RL=100Ω.
    It is allowed to use any number of resistors with maximum value of 100kΩ for each.​

    I think the best topology to use is the shunt series. Is that correct? and any hints on the final structure of the circuit?

    Thank you...
