An inverting operational amplifier (op-amp) amplifies the input signal while inverting its polarity. This calculator is designed to compute for the resistors R2, R3 and R4 given the other parameters. The resulting values are in kilo-ohms (kΩ). ...
This Non-Inverting Op-Amp Resistor Calculator determines the bias and feedback of resistors for a non-inverting Op-Amp
This calculator determines the bias and feedback resistors for a non-inverting op-amp, given the gain and desired output bias point. There are many free parameters to the design so enter the value of R1, which will scale the other resistors. Use V1 as the input for the inverting Op-Amp...
Values of R1 and R2 are swapped, e.g. to get Vout in example below R1 should be 10K and R2 51K.
It is customary to consider the output resistance of the non-inverting amplifier as being zero, but why is that? An Op Amp’s own output resistance is in the range of tens of ohms. Still, when we connect the Op Amp in a feedback configuration, the output resistance decreases dramatically...
Moreover, being an ideal Op Amp, its gain is high, so the inverting input is at a virtual ground. Figure 2 If you are not familiar with the concept of virtual ground, here is an explanation. Due to the high gain of the ideal Op Amp, on the order of 100,000 (or 100 dB), when...

This is commonly known as negative feedback and produces a more stable op-amp. Negative feedback is the process of feeding a part of the output signal back to the input. But to make the feedback negative, it is fed to the negative or “inverting input” terminal of the op-amp using ...
(op-amp) amplifies the input signal without inverting its polarity. This tool is designed to compute for the resistors R2, R3 and R4 used in a non-inverting amplifier. The resulting values are in kilo-ohms (kΩ). Note that the non-inverting amplifier circuit used in this calculator has ...
Its transfer function is (1) How do you derive this function? Let’s first note that we can consider this Op Amp as ideal. As such, the current in the inverting input is zero (I = 0A, see Figure 2) and the currents through R1 and R2 are equal. ...
