  • Experiment 4 Comparators, Positive Feedback, and Relaxation Oscillators

    Experiment 4 Comparators, Positive Feedback, and Relaxation Oscillators

    Introductory Electronics Laboratory Experiment 4 Comparators, positive feedback, and relaxation oscillators This experiment will continue our investigations of nonlinear analog circuits. We consider first a simple op-amp application used to interface an analog signal to a digital device: the Schmitt trigger, a 1-bit analog to digital converter (in which the op-amp is used as a comparator). This circuit introduces us to the use of positive feedback in our op-amp designs, rather than the negative feedback we’ve used so far. In this case the positive feedback is used both to introduce hysteresis in the circuit’s state transition trigger conditions and to speed up the op-amp’s output state transitions. Next we couple a Schmitt trigger with first an RC low-pass filter and then an op-amp integrator circuit to develop relaxation oscillators, simple signal generators which work much like a ticking clock to output a repetitive waveform. Spend some time studying this relaxation oscillator idea, because its feedback scheme is applicable to many types of simple analog signal generators, clocks, and timers (some of which could more correctly be considered to be simple digital circuits). We then introduce a special-purpose integrated circuit, the “555 timer,” a versatile device we will use to build astable and monostable multivibrator circuits useful for a variety of applications. This device is our first true example of a mixed-signal circuit incorporating both analog and digital design concepts. Extending this digital design theme, we will conclude the text with a potpourri of comparator-based implementations of basic binary logic gate functions.
