EE 205 Coifman 12-2 Active circuits have one or more devices that require an external power supply to operate correctly Recall the proportionality property: y=Kx Assuming y and x have the same units (A or V), what is the maximum that K could be for the circuits we have studied so far? Signal amplification:

EE 205 Coifman 12-4 Warning, Linear dependent sources are MODELS used to represent complicated circuits and or phenomena, they do not represent discrete devices. The presence of active devices makes our analysis a bit more complicated. .. + - + ri 1 ri 1 ri 1 - i 1 i s Source on + v O = v O = - i 1 = 0 Source off + - E.g., superposition principle, The response due to all independent sources acting simultaneously is equal to the sum of the responses due to each independent source acting one at a time.
