Definition of bjt
WebTransconductance (for transfer conductance ), also infrequently called mutual conductance, is the electrical characteristic relating the current through the output of a device to the voltage across the input of a device. Conductance is the reciprocal of resistance. Transadmittance (or transfer admittance) is the AC equivalent of … WebSep 28, 2015 · 100 uA : 120 ohms. 300 uA : 50 ohms. 1 mA : 35 ohms. 3 mA : 25 ohms. 10 mA : 20 ohms. This is what the transistor does, in terms of voltage noise (thermal noise, Johnson noise). Now compare these "noise resistances" with your noise budget and choose your collector current accordingly.
