    Common Drain - Source Follower JFET Amplifier Capacitors

    The original diagram is the identical i attach above. In the notes, only the diagram exists and the equations in order to find the values of resistors. Nothing more. Moreover, during the courses, in the class, we have only dealt with BJTs. As for the current gain, we divide the current we take...

    Common Drain - Source Follower JFET Amplifier Capacitors

    Its the circuit in our notes. Nothing changed. Only the values of resistors calculated from the equations given in our notes. RS1 is 8.2 ohm. In general, its the resistance Rs, which we calculate with this equation: Rs= (Vdd-Vdsq)/Idq, and then it gives us a type where we calculate RS1 in...

    Common Drain - Source Follower JFET Amplifier Capacitors

    Thanks a lot for the quick replies. Well, the design of the circuit assures that we have current gain of 30. I think, this is solved by the choice of resistors. Also, we dont care about voltage gain. Considering now the range of frequencies, its up to me,so as a typical value I determine the fL(...

    Common Drain - Source Follower JFET Amplifier Capacitors

    Hallo! New to this forum. ;) Although my main activities involve networking and IT consulting, i am attending courses for a telecommunications postgraduate. Among the courses, there is one concerning some basic circuit designing using breadboard. The previous labs were ok, but now i am stuck in...
