Those I mentioned in the title are already shown us as examples. Can anyone please advice me a circuit type for my homework? It can be for any purpose, it doesn't matter as long as it is not very complex. Thanks!

 

What do you want to dim and how do you want to power it?

 

No, no. My professor said me to design some random circuit and analyze it's components. It is not for a specific purpose. Any circuit is acceptable apart of the examples he gave (in title)

 

Hello,

Your request is to broad to have a dedicated answer.
Have a look at google:
dimmer circuit
LC circuit

Design a transistor bridge circuit.

 

Design a simple op circuit with gain (say 10).
Determine its frequency response, and max output voltage.
As a bonus determine its DC output offset due to the input bias current and offset voltage.
