Typically, a V CE increase of 10V will reduce V BE by 1mV to 2mV with constant collector current. With a constant V BE collector current will increase ~4% to 8% for a 1V increase in V CE.; With these rules in your toolbox, you are equipped to tackle pretty much any large-signal BJT …
WebBipolar Junction Transistor or BJT Current Mirror An often-used circuit applying the bipolar junction transistor is the so-called current mirror, which serves as a simple current regulator, supplying nearly constant current to a load over a wide range of load resistances. WebBJT is a semiconductor device that is constructed with 3 doped semiconductor Regions i.e. Base, Collector & Emitter separated by 2 p-n Junctions. Bipolar transistors are manufactured in two types, PNP and …
WebMay 22, 2024 · So how do we determine the range of possible values of collector current and collector-emitter voltage in any given DC BJT circuit? One answer is to employ the concept of the DC load line. In general, a load line is a plot of all possible coordinate pairs of \(I_C\) and \(V_{CE}\) for a transistor in a given circuit. WebMay 8, 2024 · The BJT operates in the saturation region when its collector current is not dependent on the base current and has reached a maximum. The condition for this to happen is that both the base-emitter and the base-collector junctions should be …
WebApr 20, 2011 · 1) Its collector resistor is 10k and just before the transistor saturates its collector resistor has a max current of 5V/10k= 0.5mA. 2) When it is saturated the collector voltage will be about +0.6V so the 10k collector resistor will have 5.6V across it. 3) Then the max collector current in this circuit is 5.6V/10k= 0.56mA.
