    I am having difficulties on how to start the design.
    Could you please guide me through this?

    Goto DigiKey.com. Do a parametric search for OpAmps that might do it. If not, what external circuitry might you have to add?

    Take a look at the topology and Bill of materials on this website:
    http://www.instructables.com/id/Op-amp-based-PWM-genarator/

    You want your harmonic distortion in this example to be the pulse width modulation out (PWM he has) to have that harmonic behavior your teacher describes. Take a look at the BOM study the op amp data sheet he describes and I did not help you.

    With only two BJT ?? Impossible, but you could try.
