Here's a growing collection - just like the SPICE circuits - of Excel based electronic circuit design tools. Download and run them as is. Or use them as templates for your own custom design tools.

Op Amp Basic Inv, Non

Calculate gains and voltages of basic Inverting and Non-Inverting amplifier configs.

Op Amp Diff Amp

Calculate positive and negative voltage gains and output voltage.

Op Amp I to V Converter

Convert input current to an output voltage (trans-impedance amp) with offset voltage.

Op Amp Bandwidth, Settling Time

Given amplifier gain and Unity Gain Frequency, find the signal bandwidth and settling time to any percent.

Op Amp Input Offset Voltage Errors

Find op amp output errors due to Input Offset Voltage, both initial and temperture drift errors.

Cp Amp Input Bias Current  Errors

Fnd op amp output errors due to Input Bias Current, both initial and temperture drift errors.


RC LP Filter Frequency Response

Calculate the magnitude (decibels) and phase of an RC Low Pass Filter (single pole transfer function) on a log freq scale.

Calculate Decibels

Convert ratio to decibels. (Simple VBA starter.)
