Missed schematics at the section AT2 at the end of Chapter 9 in the wiki, namely “AT2 Bootstrapping for Higher Input Impedance”


As I pointed in the subject line, the schematic is absent in wiki's Chapter 9 at the end of the page in the section named AT2 Bootstrapping for Higher Input Impedance

Namely, figure AT2.1

Could the curator or keeper of wiki fix it, please? Or point me to a correct direction or link or something else.
