What are the three figures of merit for an operational amplifier?
The three figures of merit for an operational amplifier are
1. Gain : The gain of operational amplifier is defined as ratio of output to input applied to operational amplifier .
2. Bandwidth : it is a range of frequencies where the operational amplifier output gives required performance .
3. Noise : it is a measure of how much noise is introduced in a process of amplification of operational amplifier
What is more critical for reducing the gain distribution of an operational amplifier and why is that so? Operational amplifier selection or resistor selection?

2. Consider this non-inverting op-amp amplifier This non-inverting amplifier circuit uses an operational amplifier as a building block. Do around. The op-amp's gain is a "little a"), but the overall amplifier's gain is A Cbig A. Derive the value of the output voltage, ve, as a function of the input voltage not confuse the non-inverting amplifier with the operational amplifier that it is built a. and the op-amp's gain a. What is the overall amplifier's gain Avo/v? (20pts) b. We...
Why is it impossible to create an ideal operational amplifier?
The last stage of operational Amplifier is a power amplifier. Class B is a good choice for the power amplifier. However, class B suffer from crossover distortion. Several methods are used to correct this non linearity as was discussed in the lecture (class AB). One of this method is the use of VBE multiplier. Design the output of an operational amplifier using class AB that employ VBE multiplier. For temperature stability RE can be used for the NPN and PNP...
solve it on paper neatly An inverting operational amplifier is to operate according to the following specification: Voltage gain = 100 Input resistance (at mid-band) = 10 ke Lower cut-off frequency = 250 Hz Upper cut-off frequency = 15 kHz Confirm a circuit to satisfy the above specification using an operational amplifier I
