Bjt as an amplifier numericals
WebThe circuit of common-emitter configuration for a npn BJT is shown in the attached figure. When it is used as a switch, the closing and opening of the switch is controlled by using input voltage V BB. Applying KVL, V BB=I BR B+V BE V CE=V CC−I CR C In cutoff region, V=V BB=0V, BE and CB junctions are reverse biased, I B=0,I C=0,V o=V CC WebShow for the design that results in the largest signal at the collector without the BJT leaving the active region, that R CI C = V CC −V BE −Vˆ be 1+ Vˆ be V T and find an expression for the voltage gain obtained. For V CC = 10 V, V BE = 0.7 V, and Vˆ be = 5 mV, find the dc voltage at the collector, the amplitude of the output voltage ...
