Spice users can run into two types of problems with op-amp models: They need a model that is unavailable in their Spice library, or their library model may produce inaccurate simulation results for ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...

Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...

A free online design tool for Intersil op amps includes an interactive tool for selecting and simulating the firm’s devices. Called iSim, the tool uses input and output specifications provided by the ...
