Rodriguez, Yoanna Electric Circuits 211L 4-8-2019 Experiment #8B: Op Amp Circuits Methods Operational amplifiers (Op Amps) are electronic circuits that amplify voltage difference between two input terminals. Using a min-DIP, the appropriate connections were made. For this Op Amps to function properly, 3 power supply connections are required: V+, V-, and ground, with V+ and V- having the same magnitude and the ground connection being the negative terminal of the +15V supply to the positive terminal of the -15V supply. Two different types of Op Amps were created by using a proto-board and connecting wires: Inverting Amp Topology, and Noninverting Amplifier Topology. For both amplifier circuits, the output was connected to an oscilloscope and a second scope input to the signal generator. For Inverting Amplifier Topology, the input voltage and the output voltage were measured using the signal generator. The frequency of the input signal was increased until the output voltage dropped to 70% of its value at 1kHz. This same idea was repeated when the feedback
