Practical OpAmp Integrator Lab
Objectives:
Design a practical integrator using an "ideal" operational amplifier and
characterize its performance in various regions of operation.
1. Design a practical integrator to operate accurately at f = 5kHz (and above)
and with the magnitude of the gain = 1 for a 5kHz sinewave input. Use standard
values for resistors and capacitors. Your design must not clip for any of the
input waveforms in Section 2 below.
3. Construct the circuit designed in Section 1 above:
A. Verify its performance.
B. Verify the predictions made in 2A through 2E above by sketching your measured output.
4. Construct a model of your "ideal" op amp, and simulate your integrator on PSPICE for
the waveforms in Section 2. Compare results by sketching your simulated output waveform
with predicted and measured waveforms.
