Why is the common-gate amplifier configuration the only JFET type amplifier that amplifies the signal and keeps it in phase?
Homework Answers
1.Common gate Jfet configuration provides a low input impedence while offering a high output impedence .As gate is grounded act as a barrier between input and output provides higher isolation.The jfet maintains the same phase in these amplifiers.
