walid Posted July 19, 2005 Report Share Posted July 19, 2005 When someone want to make a design using a BJT as amplifier, he needs to determine the early voltage of that BJT. How one determine it, or are there any standard approximations of it?Thanks. Quote Link to comment Share on other sites More sharing options...
audioguru Posted July 20, 2005 Report Share Posted July 20, 2005 The Early voltage is the rise in a BJT's collector current with increasing supply voltage when the base current is constant. It was discovered by a guy with the name of Early and is shown on a transistor's datasheet. The Early voltage and a transistor's distortion can be cancelled with negative feedback from an emitter resistor or biasing the base from the collector.
