There are too many people who call ‘bypass capacitors’ ‘de-coupeling caps’ because someone ... which you get back by bypassing the emitter resistor with a capacitor. Report comment. Reply.

You typically want the reactance of the capacitor to be about 1/10th of the emitter resistance at the frequency where you will accept a 3dB drop off. Three values of bypass cap Three different ...

One remedy for this problem is to use active bias control as in the following sketch. Figure 2 Active bias circuit . With active bias, the Vce of the gain transistor equals the rail voltage minus one ...

C1 is bypass capacitor and C2 is coupling capacitor. RL is load resistance. The results of spice simulation using LTspice is shown in Figures 7 and 8. Both the original circuit and the model produce ...
