WebIn order for a transistor to properly function as a current regulator, the controlling (base) current and the controlled (collector) currents must be going in the proper directions: meshing additively at the emitter and … WebrEE = 26mV/1mA = 0.26Ω Rin = βr EE = 100 (26) = 2600Ω. Moreover, a more accurate Rin for the common-collector should have included Re’. Rin = β (R E + r EE) The above equation is also applicable to a common-emitter configuration with an emitter resistor. Input impedance for the common-base configuration is Rin = rEE.
WebIn cutoff mode, the brake is engaged (zero base current), preventing motion (collector current). Active mode - is the automobile cruising at a constant, controlled speed (constant, controlled collector current) as dictated by the driver. Saturation - the automobile driving up a steep hill that prevents it from going as fast as the driver wishes.
