Summary

Using CircuitLab's parameters feature, we've built a parameterized non-inverting amplifier which calculates its own resistance values.


Description

This schematic uses two parameters, Gain and Rdiv, to drive the calculation of the values of resistors R1 and R2.

Run the frequency domain simulation, currently set to sweep over the Gain parameter, to see the gain-bandwidth tradeoff typical of a one-pole amplifier system. (Try changing the sweep to be over the Rdiv parameter to examine the effect of output impedance loading as Rdiv gets small!)

Run the DC Sweep simulation to see the calculated resistor values at different gain settings.
