Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

While most readers are knowledgeable about voltage doublers, here is a discussion about how to use them in unusual ways to enhance power supply circuits that might be otherwise limited in features.

STAR4003 is designed in a TSMC 40nm process with 3.3V tolerant devices. It outputs an open loop doubled voltage from the input supply. The IP integrates two NMOS power switches and two PMOS power ...

[Jonathan Thomson] just finished writing up his entry for the 7400 logic contest. It’s a voltage doubler that uses a 74HC14 logic chip. Because this is not at all what the chip was meant for–and he’s ...
