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, ...

Consider this simple common emitter amplifier (I modeled it in PartSim, if you’d like to open it): In this particular case, there are several key design parameters.

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

A circuit that lets a radio send and receive data simultaneously over the same frequency could supercharge wireless data transfer.

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable pr… ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

Monitoring network traffic more efficiently Programming language plus simple circuit design could let routers report on their own operation Date: August 24, 2017 Source: Massachusetts Institute of ...

The simple circuit design in Figure 1 lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the ...

The interface is simple and pretty intuitive, leading to an overall fun experience. This project will incorporate simple circuit design and functional programming techniques, overall it is a project ...
