WebJan 3, 2024 · The Early effect, along with the Ebers-Moll model forms a solid base for the DC analysis of BJT circuits. Here is the “rule of thumb” – depending on the transistor, the Early effect will mean that collector current will typically increase 2-20% over a 10V collector-emitter voltage range, for a given set of base-emitter conditions. ...

The Early effect, named after its discoverer James M. Early, is the variation in the effective width of the base in a bipolar junction transistor (BJT) due to a variation in the applied base-to-collector voltage. A greater reverse bias across the collector–base junction, for example, increases the collector–base … See more In Figure 1, the neutral (i.e. active) base is green, and the depleted base regions are hashed light green. The neutral emitter and collector regions are dark blue and the depleted regions hashed light blue. Under increased … See more In the forward active region the Early effect modifies the collector current ($${\displaystyle I_{\mathrm {C} }}$$) and the forward common-emitter current gain ( See more • Small-signal model See more The Early effect can be accounted for in small-signal circuit models (such as the hybrid-pi model) as a resistor defined as $${\displaystyle r_{O}={\frac {V_{A}+V_{CE}}{I_{C}}}\approx {\frac {V_{A}}{I_{C}}}}$$ in parallel with the … See more
