Prerequisites

Instructions

List of Components: Each group must have the following Get the component kit from IE lab after 3pm.

Experiments

Information for experiments will be put up on this page in advance so that you can come prepared to the lab. Familiarise yourselves with the characteristics of the components by reading the data sheets of the components given below. Many experiments are based on using CMOS inverters as transconductors. Understand the principles by going through this lecture.

Component data sheets

Go through these data sheets before wiring up the circuit. Pay particular attention to pinouts, power supply polarity, and maximum voltage ratings.

See this link for a short description of different capacitor types. Use polyester film capacitors(yellow box) for filters.

Debugging

Whenever a circuit isn't behaving as expected, it pays to go through these steps systematically. This also applies when you simulate circuits and the results aren't as expected.
