Keeping op-amp outputs “live” at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.

Charge pump circuits represent a pivotal technology in modern power management systems, utilising capacitors switched at high frequencies to convert a low input voltage into a higher, regulated output ...

A microwatt charge-pump boost converter from two ultra low power op amps. Boosting the output voltage of common alkaline button-cells to at least 1.8V needed by microcontrollers provides an “always on ...
