ABSTRACT |
|
This presentation is an extended encore of a
contributed paper delivered at the 2011 Asian Solid-State
Circuits Conference (A-SSCC) in Jeju, Korea. |
|
Digital “assist” circuits can improve the
efficiency of traditionally analog circuit blocks, especially as
technologies scale to the detriment of analog blocks. We apply some of
these techniques to a 10 Gbps optical reciever, and demonstrate 395 fJ/b
energy efficiency. Digital calibration blocks wrapped around a simple
analog core enabled offset compensation, TIA biasing, and DLL re-timing,
and cost negligible performance and power overhead. The assist circuits
cost around 40% area overhead. |

Philip
Amberg received his BS Engineering degree from Harvey Mudd College,
Claremont, CA in 2008. After graduating, he joined the VLSI Research
Group at Sun Microsystems Laboratories, Menlo Park, CA, which is now
Oracle Labs. During this time, he enrolled in the MSEE program at
Stanford University and graduated in January 2012 with an emphasis in
analog and digital circuit design. At Sun/Oracle, he has worked with
chip-to-chip I/O technologies such as Proximity Communication and
optics. He has also experimented with low-power database processing for
large scale analytics. |
