  • 2.05: Supercharged with Silicon!
    ; it loosely resembles the task-switching software on the computer this is being written on. The Prompaq is the ultimate car-tuner's toy, enabling a driver to select from various performance programs, depending on the application. Say you want a towing strategy that pushes gearshift points up, even
  • Considerations for Driving Power MOSFETs in High-Current, Switch Mode Regulators
    The low on-resistance and high current carrying capability of power MOSFETs make them preferred switching devices in SMPS power supply design. However, designing with these devices is not as straightforward as with their bipolar counterparts. Unlike bipolar transistors, power MOSFETs have

  • Embedded Systems go on a Power Diet
    in the ac/dc power converter. Another area drawing attention is that of soft switching, more commonly known as zero-voltage or zero-current switching. Soft switching has long been viewed as a way to cut down on the generation of electromagnetic interference. In an energy-efficient world, however
  • Sensing Light with a Programmable Gain Amplifier
    of the PGA / Analog-to-Digital (A/D) conversion allows the photo sensor input signal to be sampled and quickly converted to the digital domain. Switching from channel-to-channel is then easier with the Serial Peripheral Interface (SPI TM) from the PICmicro microcontroller to the PGA. Sensing Light
