WebMar 19, 2024 · The BJT as Switch REVIEW: Transistors may be used as switching elements to control DC power to a load. The switched (controlled) current goes between emitter and collector; the controlling current goes between emitter and base. When a transistor has zero current through it, it is said to be in a state of cutoff (fully nonconducting).

WebImage 2 shows a schematic for using an NPN BJT as a simple one-transistor amplifier. You will need an electret mic and an audio transformer with a 1kΩ primary and an 8Ω secondary. The circuit itself is not very powerful, and is better used as a simple demonstration. Build: Place the NPN BJT on the breadboard with the flat side facing you ... WebOct 13, 2014 · The op must clearly have an emitter resistor given what he says for the current. Q1 is an emitter follower, so R3 is not needed. If you want to scale the design to use a higher voltage source ie 12v instead of 5 for example you would want to use PNP transistors for the high side switching and than you would need a base resistor. highways approved contractors

This amplifier is based on a two-supply emitter bias circuit. The notable changes are the inclusion of an input signal voltage, Vin, and a load, RL. So that these components do not alter the bias, we isolate the input and load through the use of coupling capacitors Cin and Cout.
