Example test questions
The questions below are examples of questions you will get on the test. The solution of these
questions can be found on WEBLINK. On the real test, you well get only three questions.
Q1: For the circuit below, draw the bode plot (magnitude and phase).
R1=10k , R2=1k , R3=5k, R4=5k, C1=100nF, C2=100nF
Q2: calculate all DC voltages and DC currents of the circuit below. D2 is a zener diode with a zener
voltage of 6.8V. D1 is a regular diode. The bipolar transistor has a beta of 200
R1= 10k, R2=1k, C1=100nF, VDD=12V
Q3: For the circuit below, calculate the required width W of the transistors such that the DC voltage
at the drain equals 6V
RG1= 10k
RG2= 2k
Vt= 1V
VDD=12V
RD= 10k
L = 1um
K = 300uA/V2
Q4:
For the circuit below, draw the input and output voltage versus time.
The input voltage is a sinewave with an amplitude of 4V and frequency of 1kHz. R1=1k, C1=10nF.
Q5: For the circuit below, draw the output voltage versus time when the switch closes.
R1= 10k
R2= 10k
D2 = zener diode with Zener voltage of 6.8V
C1=100nF
VDC=18V
Assume Vout is zero volt when the switch closes
Q6: For the circuit below, draw the input voltage and output voltage versus time. The input voltage
is a sinewave with an amplitude of 4V and a frequency of 1kHz. R1=5k, R2=1k. The Opamp has a
symmetrical DC supply of +12V and ‐12V.
