Signal Sources, Conditioners and Power Circuitry

Occasionally, we are tasked with designing circuitry for a specific purpose. The request may have customer origins or it may be an in-house requirement. Alternately, a circuit may be developed because its possibility is simply too attractive to ignore1. Over time, these circuits accumulate, encompassing a wide and useful body of proven capabilities. They also represent substantial effort. These considerations make publication an almost obligatory proposition and, as such, a group of circuits is presented here. This is not the first time we have displayed such wares and, given the encouraging reader response, it will not be the last2. Eighteen circuits are included in this latest effort, roughly arranged in the categories given in this publication’s title. They appear at the next paragraph.
