Anthony Smith has designed a simple load switch using two transistors and some resistors. The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the...

Sanket Gupta @ octopart.com discuss on how to choose a connector. He writes: Continuing our series about choosing parts, inspired by the latest version of the Common Parts Library, let’s take a close look at how to find and select connectors. In this blog, we will explain all the...

Paul Rako@ edn.com discuss about thermal design in electronics and how to design your board to dissipate it effectively. If you have high-powered LEDS, or a power supply, or are trying to control larger motors, you have to get a lot of heat out of your circuit boards. The classic way...

The speed of light in vacuum is a well-known universal constant and is considered to be the nature's ultimate speed limit. No matter, energy, and information can travel faster than this speed. The speed of light has always been a topic of great interest and significance throughout...
