OIP2 Testbench

Use the OIP2 Testbench block to verify the output second order intercept (OIP2) of an Amplifier block.

Open the model.


Open the amplifier block and change the following under Nonlinearity:

  • Intercept points convention = Output

  • IP2 = 10

In the OIP2 Testbench block, clear the following:

  • Simulate noise (both stimulus and DUT internal)

  • Show Response spectrum

Run the model. You will see that the display shows a OIP2 value of 10 dB.
