Step-by-Step Analysis

We start by identifying the circuit relationships at the op-amp inputs. The configuration is an ideal op-amp with negative feedback, so the voltage at the inverting input equals the voltage at the noninverting input (v- = v+). First, analyze the noninverting input network. The node at v+ is connected to v1 through a 10 kΩ resistor, to v2 through a 20 kΩ resistor, and to ground through ......Login to view full explanation
