I need a P-channel depletion-mode MOSFET for a circuit I'm building. However, there is no model available in  that I have found, nor is there any available that I have found to buy online.   How can I simulate this kind of MOSFET in LTspice, and where can I get one?
Does anyone know how to model a depletion mode N channel MOSFET in spice?  I have looked online however the majority of resources have shown how to model a depletion type or enhancement type. I specifically want to model a FET that is fully on when there is a 0 Vgs voltage.  Resources i've looked at
Show that for any $k$-cycle $(a_1 a_2...a_k) \in S_n$, and for any permutation $\pi \in S_n$, $\pi(a_1...a_k)\pi^{-1}=(\pi(a_1)..\pi(a_k))$ prove inequality through mean value theorem Find the sum $\frac{1}{2\cdot 3}+\frac{1}{3\cdot 4}+\dots+\frac{1}{99\cdot 100}$ Please help me calculate the following sum     $$\frac{1}{2\cdot 3}+\frac{1}{3\cdot 4}+\dots+\frac{1}{99\cdot 100}$$ How do I save/remember last-used window position and size for applications? What is the meaning of $\exp(\,\cdot\,)$? What is the meaning of the notation $\exp(\text{expression})$ ?  I think that it's something of the form $a^\text{expression}$ but does it mean that the base $a=e$ or can it be any base? Is a join optimized to a where clause at runtime? Why is expected value of random variable equal to mean infinite monoid H that is not a free monoid and contains a free monoid as a submonoid Let $H= \langle h_1, \ldots , h_n \rangle$ ($n&gt;1$) be an infinite monoid that is not a free monoid. Does $H$ contain an isomorphic copy of a free monoid as a submonoid? EDIT. It is a natural question. The corresponding question for groups is the Burnside problem. adding a point in a manipulate command What do you call someone who has extensive knowledge but won't share it?

Why square the difference instead of taking the absolute value in standard deviation? rand() returns same values when called within a single function How do you disable an application specific hotkey, for example, "Command-P"? In many applications, Command-P is used to print.  My fingers are accustomed to emacs settings and reflexively press Command-P not for printing but for browsing history. It's annoying to see the print pop-up window every time when I press Command-P. I don't need a shortcut to print. How do you block a shortcut globally? How to "pretty" format JSON output in Ruby on Rails I would like my JSON output in Ruby on Rails to be "pretty" or nicely formatted.   Right now, I call to_json and my JSON is all on one line.  At times this can be difficult to see if there is a problem in the JSON output stream.  Is there way to configure to make my JSON "pretty" or nicely formatted in Rails? How to correct for small p-value due to very large sample size I am running into a problem where an independent variable, which should have no predictive power on the dependent variable based on domain knowledge, comes out with very small p-value because the sample size is very large(~100,000). If I only use &lt; 5000 data points, then the p-value becomes large enough to support the prior that the variable is insignificant. However, I don't think tweaking the sample size to get to the desired conclusion is a good practice. Is there any procedure to adjust for small p-value simply due to huge sample size? So I've been cleaning up my desktop for the last few minutes, and I tried to delete this empty folder, but it has some 3.46GB of data in it? And I'm like wtf is going on. Any ideas of why this is happening? I restarted my computer, thinking it was just some kind of fluke, but it is still happening. Open a window on a remote X display (why "Cannot open display")?
