hi there,i would like to to how to invert -2V of the sine waveform?
because i want to generate the unipolar spwm to apply n-channel MOSFET to my h-bridge.
In practically,what is the component that suitable to invert sine waveform with 180 degree with respect to 2V sinewave as show on the figure below.
by inserting the inverting amplifier at the pin 2 of op-amp,U7?
