Q1 serves as a current source "active load" for the common emitter amplifier. R4 and R5 form a biasing voltage divider supplied from Q2's collector. C2 bypasses R6 to increase the gain at signal frequencies. I've simulated this circuit in MacSpice and found a gain of about 250. This is...

I have to analyze an amplifier circuit from a microphone to a speaker and don't understand how it works. I know that the first stage is a voltage divider, but I can't figure out what the second stage is or how it works? In which stage does the amplification take place? I would rea...
Practically the working of a transistor is very simple, it can be used as a switch or as an amplifier. But for basic understanding lets start with howtransistor as a switchworks in a circuit. When a control voltage is provided to the base pin, the requiredbase current (IB)flows into the...
