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 ...

Remote Technologies Incorporated (RTI) today announced that it is now shipping its vIRsa Mouse IR emitter. Built with the professional integrator in mind, the versatile device features a sleek, ...

Hand-marked cards for applications like voting machines and meter readers often have dark marks, light marks, erasures, or dirt. Digital systems can't distinguish between an intended mark, dirt, or ...
