I've been wondering about the same "paradox", Diarmuid. And I have not come across any satisfactory explanation that explains it in terms of depletion region physics. I think it might take an explanation in terms of energy/band diagrams to clarify this seeming contradiction.
One difference...
That's a nice idea Pha5e. May be I can start working on that line.
The problem is that it needs to be a completely on-die solution without external components. Moreover, the circuit needs to be replicated at a number of places and hence needs to be as small as possible. Oh, the tyranny of IC...
Hi all,
I'm trying to temperature-compensate the impedance of a MOSFET (That is, trying to make Idrive constant irrespective of temperature variation) and am looking for simple ideas for it. Anything?
If needed, it can be assumed that there is a temperature independent reference voltage.

Hi All,
Could someone explain the properties of a MOS diode (The Gate and drain of an NMOS shorted, source and bulk grounded)? When a current I is forced through the drain, what is the voltage drop between source and drain?
Thanks,
I have a N-MOSFET(take Vt=0.5V, Vg=1V) in series with a resistor(say 1K).
I apply a voltage of 3V across the structure, with both possible polarities.
1. Which case would see a larger current and why?
2. What if Vg=3V with nothing else changed?
Thanks in advance...
Hi,
Please clarify the following questions for the circuit given. I had simulated the circuit in spice and got the confirmed results. (voltage source connected between Y and ground)
1. Why is the V/I across the resistance not equal to the R of the resistor?
2. What determines the resistance of...
level shifter tutorial
Can someone gimme a link to read about voltage level shifters using CMOS or suggest a book to read? Or can someone give example circuits?
Can some one provide the link for understanding basic interfacing circuits such as LVCMOS, HSTL, SSTL, LVDS etc. It would be better if it is simple in its explanation,,,
Cheers and thanks...
