Second section – 4 questions, available time 20 minutes
Question 1:
Draw a square wave with amplitude 1V (peak-peak), period 10 us and
offset 1V. Draw the output of an RC low pass filter with R=1kΩ and
C=10 ns, when the input is the previous square wave.
Question 2:
Draw the 3dB bandwidth of the current in a series resonating circuit
and show how to derive it.
Question 3:
CMRR: precisely describe the method to calculate and define CMRR
Question 4:
DIODES: describe the relationship between the depletion
region and the potential barrier in forward/reverse biasing conditions
