a) Find the voltage uout depending on i4 and Usat if the Op-Amp is operated in the linear region.
Now, we assume that the Op-Amp is in the positive saturation. The saturation voltage is denoted by Usat.
b)* Give uout depending on i4 and Usat
c) Determine the range for i4 such that the Op-Omp is in positive saturation.
