Homework Help: Measuring BJT DC Operating Point

  1. Oct 17, 2011 #1
    Hey guys,

    I am working on my lab with BJT with a Common Emitter Configuration. One of the steps asks me to measure the DC Operating Point, however I am not sure what they want. What I think they want is for us to find the point VCE where the slope of the collector current vs VCE intersects with the base current vs VBE.

    There's an emitter resistor? You need to determine the base current, and IC and VCE. Assume either a typical beta, or a beta of the most unfavourable end of the acceptable range.
