Accountants and MBAs use spreadsheets to play “what if” scenarios with business and financial data. Can you do the same thing with electronic circuits? The answer–perhaps not surprisingly–is yes.

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 ...

For a collector follower with emitter resistor, you’ll often find that the gain per stage is no more than 10 to 50 times. The gain increases when the emitter resistor is omitted. Unfortunately, the ...

LVPECL is an established high-frequency differential signaling standard that dates back to the 1970s and earlier when high-speed IC technology was limited to NPN transistors only. Since only an active ...

Modern interface isolators integrate interface transceivers with an internal isolation barrier. Older designs, prior to this integration, use separate, standalone isolators in combination with ...
