3- Using Op-Amp ICs and any required components, design a current gain amplifier with gain equals 50.

Suppose that we want to design an amplifier that can produce a 100-kHz sine-wave output having a peak amplitude of 5 V. What is the minimum slew-rate specification allowed for the op amp?

When 100 V and 20 V are applied to the non inverting and the inverting terminal of open loop an opamp, the output obtained is 80600 V.  If the voltage at the inverting terminal is changed to 40 V, then the output voltage is 60700 V.  What will be the differential gain and common mode gain of the opamp?

A noninverting amplifier is being designed to have a closed-loop gain of 36 dB. What op-amp gain is required to have the gain error less than 0.15 percent?

Discuss what a difference amp is, give equations and details, what is a single-ended and differential signal, what is a 4-20 mA signal, what is common-mode noise and why is a difference amp used?

what is op-amp and its characteristics?

Why are the two circuits called inverting and non-inverting amplifier, respectively?
