Bjts as amplifiers

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 ... WebThen bipolar transistors have the ability to operate within three different regions: Active Region – the transistor operates as an amplifier and Ic = β*Ib Saturation – the transistor is “Fully-ON” operating as a switch and Ic = I (saturation) Cut-off – the transistor is “Fully-OFF” operating as a switch and Ic = 0 A Typical Bipolar Transistor

WebSep 2, 2024 · \$\begingroup\$ Actually BJTs do work as current amplifiers at the low level. For a NPN, for example, to get electrons out the base, lots more electrons have to be injected via the emitter, since so many of them diffuse across the junction and get to the collector before they can go out the base lead. WebELE200 Laboratory SMALL-SIGNAL BJT AMPLIFIERS OBJECTIVES 1) To understand the operation of the common-emitter (CE) amplifier 2) To learn the effect of a bypass capacitor on amplifier voltage gain (Av) THEORY Transistor A transistor is a non-linear, active three-terminal device that acts as a voltage-to- current converter.
