Discussion:
1- What kind of restrictions Non- inverting op-amp face compared to
inverting op-amp?
2- State 5 different types of op amp. Demonstrate them briefly then
draw the circuit diagram for each kind.
3- For an inverting op amp, if the voltage input peak equal to 10.2 V,
R=10KQ and RF 2002, find Vo and the voltage gain. Assume the
input signal has a sinusoidal behavior.
4- Consider an OP amp connected to the inverting configuration to
realize a closed-loop gain of -50 V/V utilizing resistors o f 1 k2 and
50 kQ. A load resistance RL is connected from the output to ground,
and a low-frequency sine wave signal of peak amplitude Vp is
applied to the input. Let the OP amp be ideal except that its output
voltage saturates at +/- 10V and its output current is limited to the
range +/-15 mA.
For RL = 1 k2, what is the maximum possible value of Vp while an
undistorted output sinusoid is obtained?
Q2) Why is there a difference between the theoretical
and practical values of voltage gain in an inverting and
non-inverting Op amplifier?
