It is important to solve several OpAmp circuits since they will need them later to do active filters. Start by revisiting how to write Node Voltage equations but substitute a Z in place of an R .: Z V V I B A ~ ~ ~ = Then jump directly into an example. The node equations are: 1 2 C 2 B 1 1 2 C 2 1 B 1 C 2 B C C B 2 C B 1 A B B 1 A 1 1 1 1 1 1 I L j R V R V R V R V C j R R V I L j V R V V V C j V R V V R V V V V V ~ ) ( ~ ) ( ~ ~ ) ( ~ ) ( ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ = ϖ + + = ϖ + + = ϖ + → = ϖ + + → = These can then be solved using one of several methods to find B V ~ and C V ~ . Next, discuss Mesh Equation analysis and use the same circuit: 2 1 2 B A 1 C 1 B 1 A 1 C B 2 C B A B B B A 1 C A 1 A R I L j R I I R I V I R I I I L j I R I I I I I I I R I I V I C j C j C j C j C j C j ~ ) ( ~ ) (...
