European Union has just published a proposal for a regulation that ‘bolsters cybersecurity rules to ensure more secure hardware and software products’. There are yet business regulations and good practices, in particular with the IoT Security Assurance […]
Sometimes you quickly read a post or an article, get the core information, process it in low-priority mode (because you don’t feel concerned) and trash it in your deep sea memory. It’s probably what occured […]
JFETs are key elements in high-impedance devices like MEMS sensor buffers, microphone preamplifiers or Moving Magnet (MM) phono preamplifiers. (Don’t misfit with MOSFETs!). Nevertheless, there are somehow controversial components for Hi-fi aficionados. Generally, BJTs high […]
Capacitors come in two main types: electrolytics and non-electrolytics. There are not ideal elements, less to say, and intrinsically present Equivalent Series Resistance (the famous ESR), current leakage, dielectric absorption and, as usual with real […]
Resistors have two main issues when you want to design a low noise, low distorsion system : noise and linearity. Imagine also that you design a RIAA filter : tolerance and linearity are major concerns […]
The LoRa Alliance has announced that public LoRaWAN networks have grown by 66 percent over the past three years. LoRaWAN is an open standard for IoT low-power wide-area networks (LPWANs). The LoRa Alliance has more than 500 […]
