I can think at least a handful of parameters. Why stop at 2?nobodyhere said:Homework Statement: I'm wondering what are the two key parameters used to describe a non-ideal Op-Amp? And what are the limiting values of these two parameters in the ideal limit?

An operational amplifier, also known as an op-amp, is an electronic device that amplifies the difference between two input voltages. It is primarily used in circuit designs to perform mathematical operations such as addition, subtraction, multiplication, and division.
The key parameters of an operational amplifier include gain, input and output impedance, bandwidth, slew rate, and offset voltage. These parameters determine the performance and limitations of the op-amp in a circuit.
Gain, also known as amplification, is the ratio of the output voltage to the input voltage. It is typically measured in decibels (dB) and determines the level of amplification an op-amp can provide.
Input impedance is the resistance that an op-amp offers to the input signal, while output impedance is the resistance that the op-amp presents to the output signal. These parameters affect the accuracy of the input and output signals in a circuit.
Bandwidth is the frequency range in which an op-amp can amplify signals without distortion. A wider bandwidth allows for a larger range of frequencies to be amplified accurately, while a narrower bandwidth can result in signal distortion.
