For this week’s QSPICE schematic capture, we have “MC Filter PB Gauss” by our friend and frequent schematic capture contributor Alexander Bordodynov.
This QSPICE schematic models an active band-pass filter and performs a Monte Carlo tolerance analysis using Gaussian-distributed component variations. By varying resistor and capacitor values across multiple simulation runs, the circuit shows how real-world component tolerances shift the filter’s peak gain and center frequency.
Why simulate it in QSPICE? QSPICE makes statistical analysis fast and practical, allowing engineers to visualize worst-case behavior, sensitivity, and production spread in seconds. That means better component selection, tighter design margins, and greater confidence that the hardware will perform as intended across manufacturing variations.
