Bjts as amplifiers
WebJan 27, 2024 · BJTs are faster (have higher bandwidth) as amplifiers devices (BJTs can move around within the "partially on" region where linear amplification occurs faster. BJTs need continuous signal current to control. MOSFETs do not (only voltage and transient currents to charge the gate-source capacitor). This is a strike against BJTs in high power ... WebJust started learning basics on BJTs (Biasing and different configs). I had done OP amps before that. How does one decide if OP Amps or Transistors are better for amplification purposes. I'm planning on making a small guitar amplifier that can take in instrument level input and output to headphones. Nothing fancy, just something for educational ...
