A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” ( Ref. 1 ) by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist. Here’s one we ...
A well known power supply circuit is the capacitance multiplier. It doesn’t regulate, but instead reduces ripple noise while the output tracks at some fraction of the input voltage (Figure 1). Figure 1. Standard “capacitance ...
