* Step 1: For open loop simulation, change the closed loop simulation by\nStep 2: 'Break the loop' at opamp negative input\nStep 3: Give the broken nodes unique names, for example 'fb' and 'inm'\nStep 4: Insert a 0V voltage source to close the loop again
* AC=1 Voltage source sets the\ndifference between 'fb' and 'inm', does \nnot force ratio of 'fb' and 'inm'.\n \nRatio 'fb/inm' is determined by \ncircuit open loop gain.
* Step 5: Give the voltage source an AC=1 stimulus
