I am studying for an exam and as a part of a question I have to explain biasing and operation of the voltage follower that uses two matched JFETs in the following arrangement:
I am not sure that I understand the self biasing of
T2 can't be positive because of the voltage drop across
R2 when a current
I flows, so
T2 will never be fully "on", putting a limit on the maximum current
I regardless of the input voltage, correct?
If that is so, is that maximum current
I in practice lower than what is needed to achieve the desired drop, for the output to be equal to input?
