Anyone else find that Spice simulations results of part a generate either a inverted pole or resistor in parallel at low frequencies (<100 Hz) resulting in a flattening of the inverted zero around 5dB? Mathematically I can only derive the inverted zero.
When you simulated the derived answer, you have to simulate an ideal opamp. I approximated this by setting the GBW to a very high value. Then the simulation matched the derived inverted zero.
ReplyDeleteThank you. I was only using gain 10 which caused the discrepancy.
