Multisim Simulation Circuit: (3) Summing Operational Amplifier
1. Inverting SummationOperational Amplifier The inverting summation is relatively simple and can be understood as the superposition theorem. Uo=-(R3/R1+R3/R7+R3/R5)*2, the factor of 2 is because the negative terminal voltages are equal; if they are not equal, each needs to be multiplied accordingly. PS: I basically haven’t forgotten this. Simulation Result 2. Non-Inverting SummationOperational Amplifier The … Read more
