Very good explanation explain the logic very well then very easy to understand . Please add more videos about other components and some design projects to familiar with electronic devices. It will be a very good step we very rarely find this type of explanations covering almost all the areas. Thank you for your effort for allocating your valuable time for this.
Sir, I have a requirement of design ce amplifier with 100 ohm output impedance and voltage gain of 25. Since the output impedance is very low, I faced some difficulties of selecting the transistor and finding Rc, Re values. Could you please give some advices!
If your Gain is 25, then Rc/Re = 25, Rc is approx the output impedance there for Re = 4 ohms, assuming a supply voltage of 12v and a Quiscent point of 7v, the collector current is (12-7)/100 = 5mA, assuming a beta of 100, the base current is 5ma/100= 0.05 ma You can calculate the R1 and R2 from the above info.
How do we design two stage direct couple transistor preamp with NF. How do we calculate output impedance ,input impedance? please explain that... (Remember: two stage)
