To those who haven't see this cool little circuit it employs the non-linearity and symmetry of the JEFET to clip a triangular signal to make it more sinusoidal

JFET Traingle 'cipper'

Can someone please explain to me how the biasing in this circuit works?

    \$\begingroup\$ Ok. That is a cool hack. \$\endgroup\$ – JRE Feb 13 '19 at 9:42
  • \$\begingroup\$ Note that the biasing isn't constant. Vgen can be positive and negative. When Vgen = 0 V, there is no biasing. An interesting circuit to try on a rainy Sunday afternoon though. I might try it out if I can find a working JFET in my parts drawer. \$\endgroup\$ – Bimpelrekkie Feb 13 '19 at 10:01
  • \$\begingroup\$ However, one should know that this circuit works "good" for a certain input amplitude only (app. +/- 2V). \$\endgroup\$ – LvW Feb 13 '19 at 12:33
  • \$\begingroup\$ Might help. \$\endgroup\$ – JRE Feb 13 '19 at 13:19
