If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used to ...

This charge-pump circuit, using just a few diodes and capacitors, ups the input voltage by a factor of 1.5 in contrast to the usual voltage-doubling output. Micropower product designs sometimes ...

Charge pumps represent an established topology for dc-dc converters that generate low-power inverted and doubled replicas of the input voltage. Typical output currents are as high as 150mA. Such ...

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 ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...

If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up and ...
