Course

Electronic Systems Thinking and Circuits

The course is intended to provide an insight into electronics systems that are commonly encountered in daily life centered around sense-compute-communicate. The course will begin with a tear down of a laptop and/ or a mobile phone and looking at the various components. The standout component on the board is the battery which naturally leads to an introduction to voltage and finite energy sources. The course will then go on to identify a couple of ICs on the board like the processor, the RF components all connected to the same power source, each drawing its own current which can be used to motivate the idea of KCL. Basic network analysis will be covered as part of the theory to go hand in hand with these topics. Simple experiments will be conducted on a breadboard to demonstrate the theory where applicable. The idea of a microprocessor and memory will be explained with the help of analogies in an abstract manner.
