As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...

"Learn how to set up and analyze an RC circuit using the PhET Simulator! In this tutorial, I’ll guide you through the step-by-step process of building a simple resistor-capacitor circuit, explaining ...

The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.
