  I remember one time I used 555 timer along with diodes and capacitors so I could have negative voltage as well as positive for running op-amps, it actually worked quite well.

  Really enjoyed this video in which you show your evolution in implementing V-boosts. &nbsp; <br>Dealing with power systems (solar) has intrigued me with using boost circuits to draw more power from my small solar array. &nbsp;Ignoring the subtleties of charging modes, a low battery can actually double the current flow, balancing out the power flow for changes in irradiance, as well as a few other tricks can cause a meaningful boost to the energy captured. &nbsp;Inductors are simpler than capacitors and less prone to failure.....they are great storage devices.

  Thank you your comprehensive video tutorial on how charge pumps and boost converters work, and the disadvantages of each type of DC-DC voltage boost cct. &nbsp; You have covered numerous important considerations in circuit design. &nbsp; Great job!

  thanks dude. this was the video i needed on charge pumps. your initial demonstration at the beginning was just the right thing to show for this to make sense.

  I’m a guitarist who likes building my own effects pedals. I have an overdrive/distortion circuit design that’s op amp based; with some tweaking to the circuit (including the inclusion of more robust components) the design offers additional versatility by adding the option of &nbsp;a “clean” boost. This though requires an increase in the headroom. <br><br>Through experimentation, I determined that 22VDC is optimal. Most power supplies &nbsp;offer 9VDC &nbsp;with a few having 1 or 2 output taps offering 18VDC. <br><br>As stated, I need 22VDC. As my circuit only requires about 100 mA, a charge pump that takes an input of 9 VDC and gives ≈ 22VDC is ideal. Thank you for talking about more than one charge pump design.

  Wow, I mean Great 👍. Finally someone speaking in favour of voltage multipliers.<br>I have used them to create negative rail voltage for operational amplifiers

  Hey thanks a lot for this video,i&apos;ve looked online for some useful charge pump circuits and came across some of the ones you showed, but the last one is by far the most practical one, despite it not being able to deliver much current.

  This was great man. I am working on a charge pump system to bias photodetectors, and when i was plugging a load, the voltage was dropping drastically, but now i know why and how to fix it. Thank you.

  much like a charge pump compares to a boost converter, there is the capacitor equivalent to the buck, it is called &quot;switched capacitor&quot; where a couple of switches and a decoupling cap are made to work as a frequency controlled resistor where resistance is inversely proportional to frequency.
