5.7. Integrator

Try these first

1. 1.

   Define what an integrator circuit does.

   Hint

   Think about calculating area under a curve.

2. 2.

   What are the two main components of an integrator circuit?

   Hint

   They are key in determining the output behavior.

3. 3.

   What is the primary function of an integrator circuit?

   • To output the derivative
   • To output the integral
   • To amplify the signal

   Hint

   Think about calculating the area under the curve.

4. 4.

   True or False: The output of the integrator circuit is directly proportional to the input voltage.

   • True
   • False

   Hint

   Focus on what the integrator actually does with the input.

5. 5.

   Design an integrator circuit for an application that requires the integration of a ramp input. Specify the values of R and C to achieve an output that does not exceed 5V.

   Hint

   Use knowledge of the ramp input characteristics to find acceptable RC values.

6. 6.

   If the input signal decreases exponentially over time, how would you expect the output of the integrator to behave? Justify your answer with calculations.

   Hint

   Think of how the exponential function integrates over time.
