<azonenberg> berndj: Within a cell, you can probably use lumped approximations just fine
<azonenberg> On that note I still want to see someone make a ~500 THz sinewave oscillator
<azonenberg> then connect to a bunch of 1/2 wave dipoles
<azonenberg> and use it as a light source
<berndj> heh. what does limit the speed of a very tight ring oscillator?
<berndj> RC relaxation time?
<berndj> trying to lay out a D flipflop a la http://vlsitechnology.org/html/cells/wsclib013/dfnt1.html but struggling to get signals to "cross over" each other without taking up lots of real estate
<azonenberg> The level-triggered D latch in the SecurID solved that problem with a metal2 jumper
<azonenberg> This is digshadow's blog, not mine, but we analyzed the chip together
<azonenberg> Note that this was from the SRAM and thus rotated 90deg relative to the rest of the chip
<azonenberg> he kept the images in this orientation
<azonenberg> Vdd is at right, i think
