Emitter Degeneration vs Cascode BJT Current Sources | Detailed Analysis (Part C4)

Video Description In Part C4 of the Cascode BJT Circuits playlist on YOMS Electronics, we take a deeper and more detailed look at two widely used techniques for improving BJT current sources: Emitter degeneration using a resistor Cascode BJT current source This video goes beyond simple comparison and focuses on why the cascode approach outperforms emitter degeneration when high output impedance is required. You’ll understand: How emitter degeneration improves output impedance—and its limits Why degeneration consumes voltage headroom How the cascode isolates the sensing transistor from VCE variations Why cascodes achieve orders-of-magnitude improvement in output impedance The practical trade-offs between simplicity, headroom, and performance LTspice simulations are used throughout to verify and reinforce the theoretical explanations.
