![]() In digital/switching applications we saturate the transistor (or MOSFET) so for design purposes we "assume" low hfe to make darn-sure it's hard-saturated when turned-on. If the gain needs to be precise we can use precision resistors. The thing that makes op-amps so easy to use is that they have very-high open-loop gain so the the gain (with feedback) can be entirely defined by two resistors. This reduces gain so for example, instead of making an amplifier with a gain of 100 you use negative feedback to get gain of around 10, or you might use a 2-transistor circuit with feedback for net gain of 100, etc. In real-world linear applications negative feedback (corrective feedback) is used so the gain is predictable and stable. However, I need this transistor not to work in saturation mode, since I. SATURATION REGION (FULLY ON) A transistor is said to be saturated (Fully ON). If your music sounds thin, weak, and digital-sounding, apply saturation to make it sound full, fat, and present. Hello all, I have a transistor which is currently working in saturation mode. active region:Saturation Region of BJT TransistorThe saturation region is one. ![]() You can "experiment" to find the true hfe (under certain conditions) as long as you stay out of saturation (where the current is limited by a resistor or "something else"),ĭrDiettrich mentioned feedback. Transistor Saturation: Transistor saturation plugins emulate the sound of audio driven through transistorbased circuits. ![]() Plus, there is tolerance (part-to-part variation) and variations with temperature. Suggested Reading Before digging into this tutorial, wed highly recommend giving these tutorials a look-through: Voltage, Current, Resistance, and Ohms Law - An introduction to the fundamentals of electronics. I'm not sure I'm following, are you're saying it's hard to determine the IC since the gain is not linear. ![]()
