Charge Pump Circuit. The simplest such circuit is. For the charge pump.
Extending the applications of 5v. Charge pumps are extensively used in nmos. Charge pumps can also be used as lcd or white led drivers generating high bias voltages from a single low voltage.
The simplest such circuit is.
For the 555 oscillator 555 timer bipolar variant 10uf electrolytic capacitor decoupling 2x 100nf ceramic. Charge pump functionality can also be embedded within ics rather just be offered as separate devices. The configuration shown here inverts the input voltage. Charge pump circuits creating high voltage.
