21. 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 ...

23. 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 ...

25. Battery switch
    Lapo Pieri
    Circuits Texas Instruments LM5050-1 LM5050-2 CSD17501Q5A
    Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The growing demand for portable devices capable of working where there is no power grid or ...
