  1. Thermal considerations matter for Class D amplifiers
    A Class D amplifier provides better efficiency and thermal performance than a comparable Class AB amplifier, but implementing a Class D amplifier still requires attention to good electrical- and...

  2. Lowpass filter has improved step response
    A common problem that arises when you design lowpass filters for signal conditioning is the filters' effect on the system's time-domain response. Because pushing the cutoff frequency lower slows the step...

  3. Circuit provides efficient fan-speed control
    As Moore's Law plunges us into the realm of multigigahertz processors and PCs with gigabytes of RAM, engineers face the task of removing the heat that these state-of-the-art components produce. Cooling such systems...

  4. Low-cost feedback circuit boosts efficiency
    To implement a step-up converter with a current output, designers often simply connect the load in place of the top resistor in a resistive-divider feedback network. The bottom resistor then serves as a current-sense...

  5. Simple Additions To Audio Amplifier Prevent Clipping At Higher Inputs
    Amplifying the human voice presents some tough challenges. One of the toughest of these is providing enough amplification to make sure a soft-spoken person can be heard while allowing sufficient headroom for people who...
