Question 1
In an ideal operational amplifier circuit configured as an inverting amplifier with the non-inverting terminal (+) connected to ground (0 V), what is the potential at the inverting terminal (−) when operating in the linear regime?
Correct Answer:
0 V (Virtual Ground)
Question 2
What is the closed-loop voltage gain Av = Vout / Vin for an ideal inverting operational amplifier circuit with input resistor R1 and feedback resistor Rf?
Correct Answer:
Av = - (Rf / R1)
Question 3
A non-inverting operational amplifier has an input resistor R1 = 10 kΩ and a feedback resistor Rf = 90 kΩ. If a DC input voltage of Vin = +0.5 V is applied, what is the output voltage Vout?
Correct Answer:
+5.0 V
Question 4
A first-order active low-pass filter uses a resistor R = 10 kΩ and a capacitor C = 15.9 nF in its feedback network. What is the -3 dB cutoff frequency fc of this filter?
Correct Answer:
1.0 kHz
Question 5
What is the high-frequency asymptotic roll-off rate (slope) of the Bode gain magnitude plot for a second-order Sallen-Key low-pass active filter?
Correct Answer:
-12 dB/octave (-40 dB/decade)
