I know what VDD generally means. I was stumped by the question that brings in terms that have simply no reference. Without a schematic, it can mean anything. I still don't know what I*(VDD)*VDD meansTechnically VDD is:

There is also VCC, which relates to the Collector of a BJT circuit.
I practice either is used to represent the DC supply voltage for a circuit. A circuit with a voltage regulator might have VBAT -->voltage regulator -->VDD or VCC for the rest of the circuit. However, if you look at various schematics across the internet or even on this site, the rigorous definitions are not strictly observed. ECAD programs, like Eagle, will remind you when the rigorous definition is violated.
Where did you see that?I still don't know what I*(VDD)*VDD means
It is pretty clear that the TS is using VDD to be synonymous with V.I know what VDD generally means. I was stumped by the question that brings in terms that have simply no reference. Without a schematic, it can mean anything. I still don't know what I*(VDD)*VDD means
I(VDD) is just current, written as a function of the power supply voltage. So it is just I, measured in the power line VDD.It is pretty clear that the TS is using VDD to be synonymous with V.
I(VDD) is just current, measured in the supply line. It should not be written I*(VDD).I know what VDD generally means. I was stumped by the question that brings in terms that have simply no reference. Without a schematic, it can mean anything. I still don't know what I*(VDD)*VDD means
Now I get it... Never saw that notation convention used before, so I was a little confused. So the two equations ARE the same given your explanation of your notation.I(VDD) is just current, measured in the supply line. It should not be written I*(VDD).
