It is also used as a thermal power source in … WebThe bases of the emitter-follower pair must be driven to voltage that is present on either of the collectors. So that means Vs or Vs + Vgs for an emitter-follower pair controlling a N-channel MOSFET on the high side. Assume that my supply voltage is something high like + 100 VDC. I'll call this Vp for simplicity. gabriel gallant sur facebook.com
