Keeping up with Moore’s Law
https://www.electronics-lab.com/keeping-moores-law/
by Clemens Valens @ elektormagazine.com: There was a time that every extra storage byte crammed into a chip was greeted with cheers and applause but today only few people will get the champagne out when an extra gigabyte or so is announced. We have become so used to the ever growing capacity of memory chips […]
Load switch with self-resetting circuit breaker
https://www.electronics-lab.com/load-switch-self-resetting-circuit-breaker/
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 load. The load current is limited by negative […]
