Bjt collector
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. WebMulti collector bjt's are useful in IC's since it is easy to match the ratio between the collector areas and split a polarizing current in precise ratios, as in the uA741 output stage polarization ( Q 13 here): At solid state …

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.
