## Electronic Circuit Design Tools

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.

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

Calculate positive and negative voltage gains and output voltage. |
||

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

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

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

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

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

Convert ratio to decibels. (Simple VBA starter.) |
