| Jun 25, 2017 at 12:14 | comment | added | stackonaut | Im confused tbh. I found this video and hes doing "exactly" what i try to understand. Why does it work what he is doing with the external battery, but mine does not as you say ? youtu.be/ZZDdlAgZfvI?t=3m22s And even then...i still dont get why with the charge pump (see first picture) the gate is 10v above source, but with the external battery that has the same voltage as the charge pump its not. | |
| Jun 25, 2017 at 11:39 | comment | added | Andy aka | If the source is at ten volts with respect to ground, the gate has to be at thirty volts because the battery sets the gate voltage twenty volts higher than the source | |
| Jun 25, 2017 at 10:41 | comment | added | stackonaut | But if voltages are relative, why does it not work with the battery. Isnt the gate still 10v higher relative to the source ( which is 10v in my example ) ? | |
