Note that you need to find ß for the transistor from its datasheet. 2N3904 Datasheet(PDF) - ON Semiconductor WebGeneral Purpose Transistors. Show calculations for obtaining the value of the constant resistor and the potentiometer:ĭetermine the Q-point values (write down your calculations in the space provided) and fill the Design column of Table 1, for lg = 100 UA. The constant resistor should guarantee that the base current should never exceed 200 uA (which is the case when the potentiometer is set to 0 2). RB So, the minimum of 1g corresponds to maximum of Rg and vice versa). Show calculations for obtaining the value of Rc + Poti R81 BB 2 V Use a combination of a potentiometer, Pot, and a constant resistor, R8, in series as the total base resistor,Rg, such that the base current,lg, may be varied from 25 to 200 uA (note that Ig = "BB-VBE). Note also that at this point you do not need to know or calculate the value for Rg. ![]() Your circuit should place a fixed collector resistor, Rc, in the circuit to prevent the collector current, Ic, from exceeding 40 mA (for this, you know that the minimum value of is zero). ![]() (Hint: Use average value) Be= Voc +10 V RB We are going to consider the common emitter configuration circuit shown in the figure to test a 2N3904 npn Bipolar Junction Transistor (BJT) under DC bias conditions.
