The base leg acts as the control and needs around 0.6 volts (V) to switch ‘on’. Once an input of 0.6 volts has triggered the base leg, a much larger current can flow through the collector or emitter ...

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 ...

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, ...
