| azonenberg | berndj: Within a cell, you can probably use lumped approximations just fine | 03:10 |
|---|---|---|
| azonenberg | On that note I still want to see someone make a ~500 THz sinewave oscillator | 03:10 |
| azonenberg | then connect to a bunch of 1/2 wave dipoles | 03:10 |
| azonenberg | and use it as a light source | 03:11 |
| berndj | heh. what does limit the speed of a very tight ring oscillator? | 03:11 |
| berndj | RC relaxation time? | 03:12 |
| 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 | 03:36 |
| azonenberg | The level-triggered D latch in the SecurID solved that problem with a metal2 jumper | 03:58 |

| azonenberg | This is digshadow's blog, not mine, but we analyzed the chip together | 03:58 |
| azonenberg | Note that this was from the SRAM and thus rotated 90deg relative to the rest of the chip | 03:58 |
| azonenberg | he kept the images in this orientation | 03:59 |
| azonenberg | Vdd is at right, i think | 03:59 |
