		<description><![CDATA[In this article, you can download a Summing Amplifier Calculator in the form of a spreadsheet.  You can input the voltage range, output range, a reference voltage and a choice of two resistors.  The calculator gives you the answer for the remaining resistors. Also, this article explains the mathematical steps towards building the calculator.

		<description><![CDATA[In a previous article, How to Derive the Summing Amplifier Transfer Function, I deduced the formula for the non-inverting summing amplifier with two signals in its input.  But what if we have 3, 4 or an n number of signals?  Can we add them all with one amplifier?

		<description><![CDATA[My daughter, Laura, a lawyer now, asked me, what is Analog?  What is Mixed-Signal Design?  She is very familiar with the word digital.  Like many people I know who are professionals in other areas than Electronics, she was born in a digital world or got very accustomed to this word.  This is mostly due to [...]

		<description><![CDATA[The summing amplifier, or the non-inverting summing amplifier, is an analog processing circuit with the transfer function (the summing amplifier formula as some say) shown in the following equation.




(1)



The first term of the product is the actual summing, while the second term is a gain due to the R3 and R4 resistors.  I prefer this [...]
