Circuit Idea/Building Circuits

The Idea
The idea of ​​the building approach is to use the elementary electrical devices as a kind of "cubes" to "build" the more complex electronic devices.

Examples

 * We can "assemble" a parallel voltage summer from the elementary electrical voltage-to-current converters, current summer and current-to-voltage converter. Later we can add an operational amplifier to it and get an almost ideal voltage summer.


 * We can build a voltage integrator from elementary electrical voltage-current converters and a current-voltage integrator.


 * Also, we can build a voltage differentiator from a voltage-to-current differentiator and a current-to-voltage converter.

Then, we can then enhance the passive circuits above using an operational amplifier. So, we can consider electronic devices as improved electrical analog devices.
