How can you identify a fixed biasing circuit

WebThis one has a resistor at the emitter so it's called "common emitter with degeneration". Nah C4 nulls out any degeneration / negative feedback, R4 just lets the fixed biasing network (R1/R2) do its job. Q1 is in a common emitter configuration (emitter has very low impedance to ground via C4 and output is taken from collector), and Q2 is common ... WebIn this case, the voltage divider biasing method is the best to use, unless you happen to have a voltage follower bias already in your circuit, in which case you can merely connect to that. Since the voltage divider is only connected to the input pin of the op-amp, which draws no current, you can make the resistors arbitrarily large. Also, if you

WebThe current through the voltage divider is about 60 uA. Assuming Vb = 6V, and Vbe = 0.7V, then the emitter current is ABOUT 2.65 mA. Collector current is (beta/beta+1) x emitter current = 2.63 mA. Corresponding base current is about 17.5 uA, which is NOT negligible compared to 60 uA, so you have to take the emitter resistor and the transistor ...
