Question 1
In an ideal operational amplifier (AOP idéal) operating in linear mode with negative feedback, what are the theoretical values for the differential input voltage ($\varepsilon = V^+ - V^-$) and input bias currents ($I^+, I^-$)?
Correct Answer:
ε = 0 V (virtual short-circuit / court-circuit virtuel) and I^+ = I^- = 0 A (infinite input impedance)
Question 2
In an inverting op-amp amplifier circuit with input resistor $R_1 = 10\text{ k}\Omega$ and feedback resistor $R_2 = 100\text{ k}\Omega$, what is the closed-loop voltage gain $A_v = \frac{V_{out}}{V_{in}}$?
Correct Answer:
-10
Question 3
A non-inverting op-amp amplifier has $R_1 = 4.7\text{ k}\Omega$ connected from the inverting input to ground and a feedback resistor $R_f = 47\text{ k}\Omega$. If the input signal is $V_{in} = 0.2\text{ V}$, what is the output voltage $V_{out}$?
Correct Answer:
2.2 V
Question 4
What is the primary function of a voltage follower (suiveur de tension / buffer amplifier) with $A_v = 1$ in an electronic circuit?
Correct Answer:
Impedance matching: provides very high input impedance and very low output impedance to prevent signal attenuation from loading effects
Question 5
In an op-amp integrator circuit (montage intégrateur) with input resistor $R$ and feedback capacitor $C$, what is the output voltage $v_{out}(t)$ for an input voltage $v_{in}(t)$?
Correct Answer:
v_{out}(t) = -\frac{1}{R C} \int v_{in}(t) \, dt + V_0
