This is unhelpful - if i was or had and experienced electronics engineer, i would be posting here :-/ In the end i solved it by myself - i used a Cmos source follower to boost the TTL signal to 0 to +15V, then 2 cmos inverters with +/-15V supplies. the first had a +ve switching point...

Sorry about this: Thinking further, what i have detailed above isn't actually enough - when the inverter output is high, i need both +15 AND -15V available, and when the output is low, (0v) i need the same outputs but in the opposite places, if that makes sense. Neither will need to supply any...

Fair answer, i was being intentionally vague because i would like to figure most of it out myself, i just hagve no idea where to start. The circuit can contain 6 MOSFETs, + resistors and capacitors, has to operate at 200MHz, and can be any size, but the smaller the better, as it has to go onto...

Hi all I have a CMOS inverter, from which i can produce something like 0V or 15V out - I don't think I can make it -15 to +15, which is what i need I believe what i need is a device called a level shifter, which would go in after but any searches online have yielded very little Can anyone even...

thumb goes in the direction of conventional current, ie in the direction a positive charge would go, so from positive to negative

Homework Statement A) A current I flows along a straight wire of cross-sectional area A. If the unit vector I denotes the direction of current flow, write down the expression for the current density J (assuming it to be uniform throughout the wire ) and give its SI units. B) (This isn't...

And i realize this looks like i haven't tried, but I've checked every set of notes, every piece of background reading provided, posted on my years facebook page, googled it, and absolutely nothing has come up.

Most likely light sources behind you, or reflection (if I understand your question).

Homework Statement A conducting rod of length l moves with a constant speed v perpendicular to an infinately long, straight wire carrying a current I. What is the emf generated between the ends of the rod when it is a perpendicular distance r from the wire? Homework Equations no idea...
