Hey guys we're learning about op operational amps and I'm having a struggle on how to transform any given circuit with an amp into its equivilant. i understand all the math involved once the equiviliant has been found, just getting to that point is a bit confusing for me.
An example i found online that can someone can use to explain the process to me:

thanks!

What do you mean by "transform"? Transform what to what?

Or do you just mean "how do you solve for the transfer function Vo/Vi"?
 

FAQ: How Do You Transform an Op Amp Circuit to Its Equivalent?

What is an operational amplifier (OP Amp)?

An operational amplifier, or OP Amp, is an electronic device that amplifies the difference between two input voltages and outputs the result as a single voltage.

How does an OP Amp circuit work?

An OP Amp circuit typically has two inputs, a non-inverting input (+) and an inverting input (-), and one output. The OP Amp amplifies the difference between the two inputs and outputs the amplified signal. The gain of an OP Amp is typically very high, and it also has a high input impedance and low output impedance.

What is an inverting OP Amp circuit?

An inverting OP Amp circuit is a configuration where the input signal is connected to the inverting input (-) and the output is taken from the same inverting input, usually through a feedback resistor. This results in an output signal that is the inverse of the input signal with a gain determined by the feedback resistor.

How do you transform a non-inverting OP Amp circuit into an inverting one?

To transform a non-inverting OP Amp circuit into an inverting one, you would simply swap the locations of the input and feedback resistors. The input signal would now be connected to the inverting input (-) and the feedback resistor would be connected to the non-inverting input (+). The output would still be taken from the inverting input.

What are some common applications of OP Amp circuits?

OP Amp circuits are widely used in electronic devices and systems, including audio amplifiers, filters, oscillators, and voltage regulators. They are also commonly used in instrumentation and control systems, such as sensors and actuators, due to their high gain and accuracy.
