Basic Ampifier for EBA
Here's a basic amplifier that facilitates a walk-through of an Error Budget Analysis. Although the non-inverting amp is a simple circuit, it provides enough complexity to showcase an EBA.

Two powerful files for the EBA are the Excel file and the SPICE file. Why?
- Excel serves as the number cruncher and organizer
- Your key to excecuting and understanding an EBA.
- SPICE provides a Sanity Check for more complex
circuits.
- Not sure if your circuit analysis and formulas are spot on?
- Run a SPICE sim to verify your calcs are correct!
- SPICE helped me discover mistakes and typos on many occasions.
Jump In! Open the files and poke around. Get familiar with the sheets and cells. Play with values, experiment.
| File Type | Link | |
| Excel | Amp1 - Error_Budget_Analysis.xlsx | Just 3 main worksheets, easy to navigate. Customizable and expandable to other circuit types and complexities. |
| PSPICE Netlist | Amp1_Non_Inv_Errors_1.cir | This netlist should run on many versions of SPICE! Just enter an error value. Does the Excel version agree with the result? |
| LTSPICE Schematic | Amp1_Non_Inv_Errors_1.asc | For you LTSPICE users, this schematic based version is ready to go! |
