| Jun 20 at 19:42 | comment | added | SamGibson♦ | @AlejandroFernández - Hi, It seems you're asking how the given schematics work, which suggests they aren't your design. To comply with the site referencing rule you should add a reference (citation) for any copied/adapted material from elsewhere, which you copy onto the site. So where did the schematics come from? If it's from another website, then please edit the question & add the website name & webpage/pdf link. It the source is offline, then add a reference "to the best of your ability" e.g. title, authors, publisher etc. TY | |

| Jun 20 at 19:27 | comment | added | Alejandro Fernández | Hi, thanks for the reply. I agree C3 should be removed. The circuit, however, is working fine and the voltage pulse is correctly generated. It is just that I dont know how to interprete the negative base current. | |
