      can you help me i want exercices and problems to practice because i have exam

  • @farhanupaul

    I can't thank you enough for your videos. You explain topics at its simplest form.

    Thank you so much for your hard work. I agree with a previous contributor....the new gain with the common base amplifier added at the front end is 1486.

    Overall voltage gain at 9.37, shouldn't be Vo2/Vin1?

  • @nilmadhabghosh3448

    The answer to the question is, gain = 1485.45 , Thanks for the video 😊

    Greatly appreciates your work brother. I didn't understand these concepts in my b.tech.

    From CC at intial cascade, the ''' GAIN (overall) = 1485.4363 "". Pls. give confirmation feedback.

    I have a question: what will be the effect of adding 2 emitter resistors (one to each stage) on the overall voltage gain equation as well as of each stage. Thank you 🙏

    • @ALLABOUTELECTRONICS
      @ALLABOUTELECTRONICS  4 года назад +2

      I have already covered it in the separate video. Because of the emitter resistor, the gain of the individual stage as well as overall gain will reduce.

    Sir I currently studying 2nd year of engineering in EEE
    But I do like the electronics the most
    But I am not able to buy the best book for the electronics . whatever books I do purchased till now are not so easy to understand
    It is effecting our studies
    So please sir do recommend the best book to learn electronics ☺
    Please sir ….............................

    So CB is used for impedance matching, so we don't get any reflection voltage? Please do some videos about high speed connections. Thank you.

    Great explanation! Are you planning on making a video purely about impedance matching? If not, my question would be if I'm planning on amplifying the signal from a Colpitts Oscillator circuit. I'd obviously need a buffer stage otherwise the circuit would be loaded and the signal ruined. In this case would a common base buffer work (since it's a high freq signal) or a common collector buffer is more fitting?
