We will be starting to use op amps in our LTSpice simulations, so it is important that you learn how to import a third-party SPICE model into LTSpice. There are a lot of good examples on the web, but I find LTspice: Adding Third-Party Models from Analog Devices to be the most straightforward. Use LTSpice and the LMC660 op amp spice model to simulate the following circuit (from problem 2). The power supplies should be 8 .vo 0.1 F vi 4.4 k 0.1 F 2.2 k a) Perform an AC sweep from 10 Hz to 100 kHz with at least 50 points per decade. Submit both the schematic and the simulation results. b) Extract the passband gain and the cutoff frequency, in Hz, from the simulation results. c) Now repeat the circuit simulation with the input set to be a sine wave with frequency equal to the cutoff frequency identified above and amplitude of 0.5 V. Run a transient simulation and show approximately five periods of both and . Submit both the schematic and the simulation results
