AM modulation

The circuit produces AM signal. The first op amp is configured as an inverting amplifier and the ri resister is replaced by a mosfet whose gate is connected to the modulating input. The second op amp gives non inverted output. Edit: a pmos was added to improve the quality of signal.

Needs work. It isn't modulating proper.

its a very bad am modulator very nonlinear and not symetric and ...... needs a lot to be perfect, anway there is visible AM signal http://everycircuit.com/circuit/5539033384747008

Your suggestions were helpful although @hurz plus note that your suggested circuit has a delay between input and am signal.

like many circuits, also filters do have a delay or phase shift. Dont be surprised. I just helped you to show @kiani there is an AM signal, but for some reasons even you cant see that, funny
