V_{DON}=0,7

First it is asked to calculate V_{0}for V_{in}=-1V and V_{in}=-5V.

Secondly it is asked to draw V_{0}(V_{in}) for -10<V_{in}<10

2. Relevant equations

3. The attempt at a solution

Using Kirchhoff Volt Law I've established that for V_{in}=-1V D1 is ON and D2 is OFF and for V_{in}=-5V D1 is ON and D2 is ON an I believe I got it right.

I have also determined that D1 conducts for a V_{in}< -0.7V and that D2 needs V_{in}<-1.4V. Right now I'm stuck at linking their current–voltage characteristic and determining the slope value, which depends somehow of the resistance values, so that I can build the V0(V_{in}) graph
