The purpose of this website is to provide elegant solutions to analog and mixed-signal design problems that have a strong basis in math. This website is not about Electronics in general. This website is about the art form of designing electronic circuits. My goal is to show hobbyists, engineering students and engineers that analog design is not complicated, so long as one understands the fundamentals and the reasoning behind the many aspects of the design. Hopefully, if they see what a wonderful art electronics design is, more will be encouraged to pursue it.

How to Derive the RMS Value of a Sine Wave with a DC Offset

I noticed a question posted on one of the Yahoo’s Q&A sites, asking what is the RMS value of a sine wave with a DC offset. The chosen answer as being “the best” was actually wrong. The next comment, which was trying to correct “the best” answer, was wrong too. I am not going to post the Yahoo link h

Apply Thevenin’s Theorem to Solve a Negative Resistance Circuit, or Current Source

The circuit in Figure 1 is a good example of applying Thevenin’s Theorem to solve a circuit with dependent supplies. It is a negative resistance circuit and it was posted in this forum with a call for solution verification for IL as a function of Vin. Since this fits very well with my plans to wri

Build an Op Amp SPICE Model from Its Datasheet – Part 4

Parts 1, 2, and 3 of this article show how to create a behavioral model of an operational amplifier based on the following parameters found in the datasheet: Input and output resistance, input capacitance, DC gain, offset voltage and gain bandwidth product. As an example I chose Analog Devices’ ADA4

Build an Op Amp SPICE Model from Its Datasheet – Part 3

In Part 2, we left off at the open-loop bode plot. We saw that it resembles the datasheet. However, our op amp example, ADA4004 from Analog Devices, shows an extra pole after 1 MHz. Indeed, the phase starts dropping after 1 MHz and becomes 45 degrees at 17 MHz. Therefore, we need another pole in our
