Laboratory in linear integrated circuits: what should technologystudent learn?

摘要

A laboratory experiment is presented for applying an op-amp-basedintegrator and level detecting circuit in waveform generation. Studentsconstruct the circuits, review the integration calculus characterizingthe circuits and observe the slew rate and limitations for severaldifferent op-amps. An explanation is given of how this experiment: (a)supports the classroom-taught theory; (b) allows for critical evaluationof the measurements; (c) builds up students' confidence in accuratemeasurement making; (d) builds laboratory report skills; (e) providesthe ability to observe the limitations of the devices from the collecteddata; (f) provides the ability to utilize data sheets thoroughly and notonly for the pinout connections; and (g) instruction on how to use theapplication notes available from the manufacturer
