Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

The basic construction of Bipolar Junction Transistor (BJT) comprises of two P-N junctions producing three connecting terminals with each terminal being given a name to identify it from the other two.

This article presents the basic analysis and design equations of a 2-transistor configuration using both polarities of transistors: the “complementary” two-BJT configuration. Transistor combinations ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...
