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 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 in parallel with the … See more Webwhere = drain-to-source voltage, = drain current and = channel-length modulation parameter.

WebThe on-state voltage of MOSFETs is a convenient and powerful temperature-sensitive electric parameter (TSEP) to determine the junction temperature, thus enabling device monitoring, protection, diagnostics and prognostics. The main hurdle in the use of the on-state voltage as a TSEP is the per-device characterization procedure, to be carried out … WebrCA= VA/ ICSAT, It is clear that the early voltage physically is one of the determinants of the collector to emitter resistance of the transistor. Similarly for MOSFET transistor, r DS= VA/ IDsat ... WebAug 9, 2014 · 39,896. I think, the term "Early voltage" applies to bipolar transistors only. It is a measure for the slope of the output chracteristics Ic=f (Vce) for Ib=const. Of course, the output characteristics for mosfets show a similar slope, which is a measure for the so-called "channel length modulation". port charles tv cast
