Good notes on wire models in digital circuits

AI Thread Summary
The discussion revolves around the need for comprehensive notes on wire models in digital circuits, specifically regarding MOSFET input capacitance, RC time loss in wires, and power distribution in a 64-bit RAM chip. The original poster expresses frustration with the inadequacy of their textbook and professor's notes. Respondents highlight that the questions posed are too vague and context-dependent, emphasizing that different MOSFETs and wire characteristics significantly affect the outcomes. They suggest that specific parameters and definitions are necessary for meaningful answers and that there are no universal solutions. Overall, the conversation underscores the complexity of the topics in digital integrated electronics.

Hello everyone.
I'm trying to do a homework in digital integrated electronics class and feel like I can finish it only if I had a good set of notes.
I have problems like comparing the input capacitance of a Mosfet to a wire of certain length, getting RC time loss in a wire, power distribution calculations on a 64bit ram chip.
Now I'm not asking for the solutions, but a good set of notes which cover these topics. So far my book is useless and the prof notes (like always) are too simplistic.

Thank You!

hi there

your queries are not really answerable as they are just too vague.

eg. EVERY MOSFET is going to have a different input capacitance and how much a
given length of wire or circuit track and their thicknesses will affect the capacitance, is going vary greatly

"getting RC time loss in a wire" --- that as it stands, is like asking "how long is a piece of string (wire)" ... as long as you want it to be
the question is meaningless without a few definitions the least of which would be the length and diameter of the wire, its resistance in Ohms / metre etc

I'm sure there's formula for wourking out much of what you are asking. and you would have to use those formulae for each and every situation you work with.
There won't be a "1 answer fits all"

cheers

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
