Silicon Labs announced a new family of secure, ultra-low-power Zigbee® system-on-chip (SoC) devices designed for eco-friendly IoT products deployed in mesh networks. The EFR32MG22 (MG22) family delivers the smallest, lowest power SoCs optimized for Zigbee Green Power applications. Based on Silicon Labs' Wireless Gecko Series 2 platform, the MG22 SoCs are an ideal choice for Zigbee devices powered by coin cell batteries or energy-harvesting sources. Target applications include smart home sen ...
Introduction   More experimenting. This time I thought I'd have a look at the output characteristics of a JFET. Sometimes these things go well and sometimes they don't. This one didn't go too well but, for all that, I'm going to blog it as I did it rather than try and tidy it up.   The output characteristic is how the drain current behaves with changing drain voltage and is usually shown for a series of fixed gate voltages. Here is an example from a datasheet. This is for a 2SK355 ...
