Circuit Design & Review

Wondering whether to choose a Sallen-Key filter or a state-variable one for your filter project? Or getting muddled over the conceptual difference between the unity-gain bandwidth and gain-bandwidth product of your chosen op-amp and how it will impact your design? Got a schematic designed by an engineer and need a sounding board or devil's advocate to look at it before you take it to market? We can help. With as little as an hour or two of review effort a week, you'll be surprised with how we can change your perspective of things.

Our passion is really in analog design, which is a fascinating and mysterious subject, much misunderstood, and now a slowly dying art and science thanks to the invasion of digital technology.
