12/8/2023 0 Comments Transistor biasing meaning![]() If you bias it at too high of a voltage, you'll get distortion on the peaks of the output signal wave. If you are biasing a transistor for an amplifier, you want to bias it so that you can get the most change at the output voltage as possible. If you filled this pool to 9ft, you would get waves that undulate from the 6.5ft mark and then spill "1.5ft" of water over the edge! If you filled the water level to 7.5ft, you would get waves from 5ft (low) to the edge of the pool. You could fill the pool to 5ft, and the waves will undulate from the 2.5ft mark to the 7.5ft mark. You can get waves that rise 5ft above the calm water level at the crest (peak) and the trough touches the bottom of the pool. Well you can't fill the pool higher than 5ft without spilling water. Let's say you want waves to be 10 ft from peak to trough. Imagine a wave pool that, when empty, is a concrete "bowl" that is 10 ft deep. With electronics, we can think of biasing a transistor as similar to setting the water level in a wave pool. It's a similar concept - we're asking: "Where is the 'neutral?'" When people say "you're biased!" in the context of, say, politics, what they mean is that you are coming from a position that isn't "neutral" (that itself is another conversation). It is a DC voltage which will alternate a small amount when combined with an AC signal.īiasing is just a method of setting some starting point.
