| Description | ||||||||||||||
| In this activity, you will study the characteristic of an operational amplifier in open-loop configuration. You will construct a sine wave to square wave convertor and a voltage comparator.
In Experiment 1, you will study the behaviour of an operational amplifier in open-loop configuration. You will connect with (1) V- earthed, (2) V+ earthed, and (3) V+ maintained at 3 V. In each case, the voltage of the other terminal will vary over a large range.
In Experiment 2, you will make use of the open-loop configuration of an op-amp to convert a sine wave to a square wave. There are three similar connections of the op-amp and they will give even or uneven mark/space.
In Experiment 3, you will study visually the variation of the output from an op-amp driven by an alternating current. |
