Choosing a Capacitor for Use as a Switch-Mode Power Supply Filter

Input filter caps need to be able to supply a quick burst of energy and to suppress noise generated in the switch circuit. Important considerations for the input filter cap are ESR, ESL, and ripple current. High CV density is preferred in the input filter caps to reduce board space, although it is more critical for the output filter caps.

Event-Driven Processor Programming

Almost since computers were invented, interrupts have been a common programming method to deal with real-time tasks. An interrupt causes a processor to stop the running task, and to execute an interrupt handler instead. The interrupt handler determines the cause of the interrupt, responds to the interrupt, whereupon control is restored to the original task. A simple example is an interrupt from a UART (a serial port) stating that a character has been received, and the interrupt handler will take the character from the UART and store it in a queue in memory for use by the main task.

Extensible Processing Platforms: Giving Designers the Best of Both Worlds

Creating a new field programmable gate array is no small feat. FPGA vendors spend tens-of-thousands of man-hours simply researching markets to determine the feature set a given device will require and the silicon process that they will use to manufacture the device. This starts years before they embark on the ever more difficult task of actually designing the IC and the software to allow users to program it.

Trustworthy Hardware for 3D Circuit-Level Integration

Three-dimensional (3D) integration is a promising technology for designing high-performance, low-power systems by stacking multiple integrated circuit dies and connecting them at the circuit level with conductive posts. Most current efforts are at the electromechanical level of getting 3D to work efficiently and cost effectively.
