Tool/software:
Hi Folks,
I'd like to understand the proper way of simulating the input impedance to an Amplifier circuit (Specifically an OPAx991) where the reference node is not GND but rather the non-inverting input. Here's the example circuit where I want to examine the impedance presented to the diode:
I've read this post: TINA/Spice: How can I "measure" the impedance in a circuit? - Simulation, hardware & system design tools forum - Simulation, hardware & system design tools - TI E2E support forums which covers the topic but doesn't exactly describe the situation we have here.
I'm curious if using the impedance meter is an appropriate approach, depicted here:
Thoughts?
