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 ...

Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...

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 ...

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, ...

The OP280 Series infrared emitter family and its matching OP580 Series sensors are designed to aid engineers in reaching design goals. The OP280 Series consists of three standard and two specialty ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...
