Internal operating voltages in electronic devices continue to decrease, but input-source voltages don't change. As the difference between input and output voltages increases, so does the improvement ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Wireless handsets, personal digital assistants (PDA) and other handheld devices can't operate everything directly from the battery since each IC requires a specific, steady and accurate supply voltage ...
