expect the other interested parties to raise their bids for Actel,
noting that the other suitors would have had ample time to
raise their existing bids before Actel’s shares went higher

Japan hangs hat

MAKUHARI, JAPAN — CEATEC, Japan’s premier consumer

hats on Google’s open-source OS for platforms such as smart-
phones and media tablets.

fMEMS shutter display ditches the filter
Hitachi Displays demonstrated a MEMS shutter display co-developed with
Pixtronix Inc. MEMS shutter displays, unlike LCD displays, need no color
filter or polarizer and are said to use light very efficiently.
The device adjusts color tones by opening and shutting the MEMS
shutter at high speed, nimbly changing the amount of light coming from
the LED backlight as well as natural light.
The specs show that the prototype display has a screen size of 2.5 inch-
es, pixel counts of 320 x 240 (QVGA), a pixel pitch of 163 micrometers
and a 120 percent color gamut based on NTSC standards.
Hitachi claims that the device can display images in reflective mono-
chrome mode with very low power consumption, suiting e-reader applica-
tions, and that it can display moving pictures at lower temperatures
compared with LCDs.

IBM’s pump-probe technique works similarly to how
a pulsed laser works. First, a pump signal is passed
into the material from the STM tip to put the atom’s
electron spin in a known state. Next, after a waiting
period, a smaller probe signal is used to make a
measurement. By repeating the process, each time
extending the delay between the pulses by a few
nanoseconds, the method can accurately measure the
electron spin relaxation time, or how long a bit of
information is retained by a single iron atom.
Today’s DRAM cells must have their bits refreshed
every 50 milliseconds or so, but by using the pulsed-
STM technique, IBM has determined that single iron
atoms would need to be refreshed about every 250
nanoseconds—about 200,000 times more frequently.
“We now know the answer to the question, ‘What
happens when you try to store information on a single

Accommodating dc-level mismatch
in multi-gigabit serial data transmission
By Eric Sweetman
AC COUPLING USING a series capaci-
tor is a simple method for coupling
multi-gigabit transmitters and
receivers. It requires only one inexpen-
sive passive component and eliminates
complications due to mismatched
transmitter and receiver dc voltage lev-
els. However, low-frequency cutoff limi-
tations of ac coupling capacitors can
limit system performance for random
and long run-length encoded data.
Careful matching of transmitter and
receiver common-mode voltages
allows direct coupling of the transmit-
ter and receiver, eliminating the need
for ac coupling capacitors. When it is
impossible to match the common-
mode voltages, dc coupling of the
transmitter and receiver can be real-
ized by using voltage-leveling circuits.
While voltage leveling circuits do add
complexity to the circuit, dc coupling
can enable significant improvements Figure 1
