Document Summary

Lec 6 9-7-16 ch2 / voltage follower / super. The voltage follower circuit basically is constructed as a non- inverting circuit but with a gain of 1 or unity. Use the superposition principle to find in the following circuit. (ideal op amp) The superposition principle means the output voltage is equal to the voltage contribution of v1 when v2 is 0 plus the voltage contribution of v2 when v1 is 0. We will denote the voltage due to v2 when v1 is 0 as and the voltage due to v1 when v2 is 0 as. Find the values of , v1, i1, i2, , il, and . Also find the voltage gain , the current gain and the power gain. Practical circuits should amplify the difference between its input signals and reject the common signals. Thus they should have an output given by.
