actually i had to design an amplifier using transistors but after i designed the two stages i discovered the impedance matching problem so i tried to use emitter follower to fix that but the transistor used to get very hot and the supply voltage dropped to around 7v. so it was either i add...
What is the purpose of those capacitors?>>>that is my question???
at very high and low frequencies..
not sure but i think no
first stage around 7 the 2nd is around 5, depends on the biasing ..
hi......I need help with understanding why when i change capacitor C5,C3 to higher value my gain is not stable. i mean when i increase the input frequency my gain will increase but at current or smaller value the gain wont change.
i want to know why , and how to calculate the value...
