- Digital potentiometers enable programmable biquadratic filterDeborah Mancuso Donald SchelleOf the many types of analog filters available to designers, few allow easy adjustments of the filter parameters. The biquadratic, or biquad, filter is an exception, however. You can change that filter's corner...Apr 17, 2025
- Infrared (IR) receiver circuit minimizes power consumptionDavid Lees Donald SchelleReceiving infrared (IR) signals while conserving system power is difficult, and typically requires the inclusion of complex power-management routines in the firmware. You can avoid that problem by disconnecting power to...Apr 15, 2025
- Accurately simulate an LEDDonald Schelle Jon RomanSolid-state-lighting applications are quickly moving into the mainstream. Although they are more efficient, the LEDs that produce the low-cost light often require a complicated driver circuit. Testing the driver...Mar 20, 2023
- Electronic circuit replaces mechanical push-push switchMechanical push-pushbutton switches (also known as alternate-action or push-on/push-off switches) can be bulky and expensive. As an alternative, an electronic version uses a cheaper, NO (normally open), momentary-on...Dec 13, 2022
- Dynamic siphon steals current from USB portA USB port offers a handy source of 5 V power for auxiliary devices. A USB port not only supplies power to a microcontroller and other essential circuitry, but also provides enough extra current head room to...Jun 2, 2022
