Current Buffer Amplifier Design

Hi Team, 

Please help me to design for the following goals.

Input : Sine wave of 6Vrms and Current = 15mA, Frequency = 5Khz.

I want amplify only the current from 15mA to 100mA and the rest of things should be constant and output wave shape should be inverted.

Expected output : Sine wave of 6Vrms and Current = 100mA, Frequency = 5Khz.

    Hello Vignesh, welcome to the e2e forums.

    Are you saying that the input impedance must be 400 ohms and the output load is always 60 ohms?

    If either impedance was different, what should be preserved; voltage gain of -1 or current gain of -6.7? (is current also rms?)
