Two zener diodes are places in parallel with one another. When forward biased, the diodes can
be modelled with a constant voltage drop of VD =0.7 V. When reversed bias, the diode is modelled
incrementally with a vontage drop VZ= 0,3V and RZ= 300Ω. iF r= 200Ω. Find the output voltage if the input is :
a. VS= 0,25V
V₀= 0,03V
b. VS= 0,5V
V₀= 0,42V
c. VS= 0,75V
V₀= 0,57V
d. VS= 1V
V₀= 0,72V
e. VS= 5V
V₀= 3.12V
