Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Keep the small-signal −3 dB bandwidth and the sine full-power slew criterion separate and evaluate each.
f−3dB≈GBW/noise gain; fslew=SR/(2πVpeak)
Worked example
GBW 10 MHz with noise gain 10 gives single-pole bandwidth 1 MHz. A 5 V peak sine with SR 1 V/μs reaches its derivative limit near 31.831 kHz, a different criterion.
Assumptions and input details
Assumes a dominant-pole voltage-feedback device. Noise gain includes the circuit feedback topology and can differ from signal gain. A query below both calculated criteria is not a specified-distortion guarantee. Additional poles, output-current/swing limits, capacitive loading and stability are excluded. No particular amplifier or circuit build is recommended.
Unit definitions
Unit selection is independent of language. Each selector contains only units for its physical quantity. Calculations use defined base units internally.
SI prefixes are explicit: for example, milli means one thousandth, micro one millionth and kilo one thousand. Changing a unit changes the interpretation of the entered number.
Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Compare inverting/non-inverting resistor gain around a reference and apply your entered output-voltage bounds.
Calculate first-order low-pass or high-pass amplitude, phase and corner frequency.
Calculate resistor open-circuit RMS noise, spectral density, short-circuit noise current and matched-load noise power.
