Medical device designers have become increasingly interested in the Linux ® operating system (OS), largely because of its open source model. Linux lets the designer leverage a large pool of developers, a rich legacy of source code, and industry-standard POSIX APIs.
But Linux may not be the right choice for all...

For a computer system to recognize a memory module, the module needs to have a chip on it that communicates the specifications of the module to the system. A system’s basic input/output system (BIOS) may depend on serial presence detect (SPD) data to properly configure and optimize the memory sub system.

One of the primary purposes of a gate driver is to enable power switches to turn on and off faster, improving rise and fall times. Faster switching enables higher efficiency and higher power density, reducing losses in the power stage associated with high slew rates. However, as slew rates increase, so do measurement and...
