Chapter 3, Problem 3.5QAP
Interpretation Introduction
Interpretation:
The output voltage
An explanation is also required as why the given circuit works as a voltage follower with gain.
Concept introduction:
The concept of virtual ground(short) is used based on which the voltage maintained at both the terminals is the same. From the given circuit the relation between the input and output voltage can be obtained using virtual short and potential divider concept. The output can then be proved observed to follow the input with a gain.
