11. Triply simply sequence supply voltages
    Stephen Woodward
    Circuits Texas Instruments CD40106B
    This circuit design for power supply on/off sequencing uses Schmidt triggers for triple-positive-rail timing purposes. Recent design ideas have explored the utility of timed power supply ON/OFF sequencing and provided circuit designs to implement ...

12. How to generate a regulated negative output from a negative input using a boost controller
    Florian Mueller
    Articles Texas Instruments LM5155 TPS40210
    How to deal with the reality that a standard buck controller power stage won’t work for negative-input conversion. Telecommunications equipment, industrial test and other applications require a negative input to negative output voltage ...

15. ΔVbe thermometer is switchable between °C and °F
    Stephen Woodward
    Circuits Texas Instruments CD4073B
    Ordinary bipolar junction transistors can sometimes be precision sensors. When you think of precision components, you usually don’t (and probably shouldn’t) think of general-purpose bipolar junction transistors. Are GP BJTs cheap and ...

16. Over-temperature micro-power alarm
    David A. Johnson
    Circuits Texas Instruments CD4013B
    The circuit is powered for years by a single 3 volt lithium battery. It sounds an alarm when the temperature exceeds a certain point. With some minor changes the circuit could also be configured for an under temperature (freeze) alarm. The circuit ...

17. Well-balanced gain, driven without pain
    Nick Cornford
    Circuits Texas Instruments LM4562
    A subtle change to a standard circuit can enhance its usefulness and even save a resistor. If there were a prize for the most trivial Design Idea (DI) of the year, this one would likely be high on the shortlist (if not at the top). Most DIs involve ...

18. Single switch controls sequential operation of multiple power supplies
    Jayapal Ramalingam
    Circuits Texas Instruments LM393
    Simple analog circuits manage multi-PSU powerup and shutdown sequences In projects containing digital and/or analog circuits, multiple power supplies are used, generally 5 V DC for digital circuits and 15 V DC for analog circuits. Some projects ...

19. Piezoelectric tap switch
    David A. Johnson
    Circuits Texas Instruments CD4013
    This circuit uses a flat piezoelectric wafer, glued inside a plastic box, as a finger tap sensor. With each tap of a finger to the box holding the wafer, the circuit turns on and off AC or DC power to an external device. The circuit is powered by a ...

20. I built a 100W stereo class-D amplifier using TPA3221
    Sagar Saini
    Circuits Texas Instruments TPA3221
    Class D amplifier with a good performance and better sound quality. We can call it a Class D with Class A specs. Story I am a fan of audio technology as it is cleared from most of my articles. I always try some new ICs or audio related things here. ...
