5.8 a) Design an inverting amplifier with a gain of 4. Use an ideal op amp, a resistor in the feedback path, and 12 V power supplies. b) Using your design from part (a), determine the range of input voltages that will keep the op amp in its linear operating region. c) Suppose you wish to amplify a 2 V signal, using your design from part (a) with a variable feedback resistor. What is the largest value of feedback resistance...

is the range of gain values
expected from such a circuit?
An inverting op amp circuit is fabricated with the resistors R, and R2 having x% tolerance (that is, the value of each resistance can deviate from the nominal value by as much as x%). What is the tolerance on the realized closed-loop gain? As- sume the op amp to be ideal. If the nominal closed-loop gain is -100 V/V and x = 5, what

What happens when vp>> vn? When vn>>vp?
Consider the Op-Amp circuit in the open loop configuration. The general curve for is shown to the right. Typically Op-Amps have very high open loop gain so their linear region is pretty small. This can make them very useful for detecting when vo > Vn and vice versa. (Hmmm I wonder if this could be helpful for the night light circuit design). Positive saturation region + | ooo Negative saturation region +-- Linear...
