Non-inverting amplifier weird Vout values
I am doing a simulation in multisim to simulate an non inverting amplifier, but i have gotten values that is not what intended. From what i know, the gain for non inverting amplifier is Va = 1 + Rf/...

h-parameter model for non-inverting amplifier
For a standard non-inverting amplifier as below:
With nodal analysis, I got $$\frac {v_o} {v_i}=\frac {R_EZ_o+aZ_iR_E+aZ_iR_f} {R_ER_f + R_EZ_i + R_EZ_o + R_fZ_i + Z_iZ_o + R_EaZ_i}$$
However, with ...

How to calculate the power supply values for an non-inverting Op amp circuit
I'm trying to figure out the power supply values for a non-inverting Op amp circuit. So far I have: input voltage= .03 mV, Gain=11, and output voltage=330mV.
I know my output voltage cannot exceed my ...

In testing this op-amp, I always get same amplification. Did I break it?
I bought these TL072 (maybe TL072CD) IC amps, for a circuit I was trying to build, but the circuit wasn't working at all so I tried to troubleshoot the amp.
I built a voltage divider ~1/1000 (on the ...

Difference in inverting and non-inverting integrator
I am trying to simulate the step response of an inverting integrator and a non-inverting integrator.
However, in the inverting integrator's output (blue plot), I see an initial overshoot in the ...
