One of, if not the hardest classes in ECE. Attend every lecture, pay attention do lots of practice and make sure to understand the material not just how to do certain types of questions. Sima is an amazing prof who knows his stuff super well and wants his students to succeed. He gives tons of previous midterms, assignments and finals so there is no shortage of practice you can do. You get out what you put in to this class.

Mainly about amplifiers. Single stage, multistage, differential, and some Op-amp stuff.

I love Sima. He seems intimidating and dry at first but he is actually super funny and cares about his students a lot. Don't be afraid to ask questions and go to his office hours
