The International Solid State Circuits Conference has selected 211 papers to be presented in San Francisco in 2011. Out of 669 papers submitted to ISSCC 2011, those chosen come from North America, 80; Far East, 69; and 62 from Europe.

One of the most notable papers to be presented is about a personal sleep monitoring system that continuously and silently monitors the EEG, EMG, EOG, and ECG signals of a person as he sleeps, developed by the Korean Advanced Institute of Science and Technology (KAIST).

Fifteen penny-sized patches are attached to the face before sleep, one of them being a network controller patch with an integrated 10mAh coin-battery. Each patch weighs less than 400mg and consumes 25microW, except for the network controller patch which uses 75microW. The total system power consumption is 425microW. An RFID-type reader is used to extract the information from the network controller patch prior to its disposal.

KAIST researchers will also present a transceiver that uses the physics of signal propagation through the human body, according to the researchers.

The transceiver has an energy consumption of 0.24nJ/b and a receiver sensitivity of 250microV. The resultant body area network uses a low-power double-FSK-modulation scheme compatible with the recently defined body area network standards.

Less intrusive use of electronic circuits for body monitoring is the application of ultra-high frequency terahertz mm-wave imaging technology as an alternative to traditional x-ray technology. The technology can be applied in not only non-invasive medical diagnostics, but security screening, and many other applications for imaging through thin materials--the recent controversy about airport screenings using scanners comes to mind.

Another paper is about a two-dimensional wideband antenna array for 3D imaging that has a rectifier detector frontend followed by a low frequency (30-100 KHz) low-noise amplifier to be presented by researchers from CEA and Universit? Montpellier.

One paper is a research from the University of Wuppertal and IHP that will detail an 820GHz frontend with sub-harmonic mixers implemented in silicon germanium BiCMOS, and using multiple antennas for beamforming.

From the University of Tokyo and Dai Nippon Printing, researchers will describe a 100V AC power meter implemented as a System-on-a-Film (SoF) using organic electronics. The design uses 100V organic PMOS rectifiers to generate a 20V supply voltage for logic, generates a line-frequency clock signal for the logic, and implements the logic using 20V CMOS organic transistors. The logic consists of a frequency divider and high-gain pseudo-CMOS inverters, all compensated for variations using a novel concept of floating gates. The design also integrates OLEDs for display purposes

The prototype consumes 2W at 100V. The research results have the potential for bulky power meters ro be replaced with inexpensive organic System-on-a-Film technology, according to the researchers.

Ken Smith, an ISSCC organizer, said the solution provides the first-ever power measurement capability using organic electronics.
