Way back when I took transistor theory our book was "Wave generation and shaping" by Leonard Strauss, and our professor (who by a curious coincidence was also named Leonard Strauss) taught us to just assume the beta of a transistor was 30 minimum, as that was the criteria for an IC wafer acceptance.
WebThe emitter current, Ie, of a transistor is the amplified output current of a bipolar junction transistor. There are several ways to find the emitter current, Ie, of a transistor. And it all depends on what information is already known about the transistor: 1st Way To Calculate Emitter Current I e. DC Analysis
