WebCommon emitter amplifier develops voltage output due to the current through the load resistor. With the solar cell darkened (no current), the transistor will be in cutoff mode and behave as an open switch between … WebOct 20, 2024 · The term hie is the ac input resistance at the base node. This resistance is identical to the slope of the input charcteristic Ib=f (Vbe). This slope is found to be hie=Vt/Ib. It also can be calculated by the ratio (current gain)/ (transconductance): hie=hfe/gm. Share Cite answered Oct 20, 2024 at 13:46 LvW 23.9k 2 22 50 No - not necessarily.

WebMar 11, 2013 · The emitter resistor serves many functions. Together with the biasing point used with the base, it sets the quiescent current for the amplifier. (In this sense, think of the BJT operating as an emitter follower.) The quiescent current will be I q ≈ V b − V b e R … WebAs of April 6, 2024, the average one-year price target for First Republic Bank is $98.94.
