hello there. I am working on ADC sar, and focus on ENOB, therefore how to increase ENOB and reduce Power consumption.123033
sar exposure of 4 W/kg for whole body has been established as a limit value Using an averaging cube of 10 g instead of 1 g of tissue mass reduce the spatially averaged sar value. Typically by a factor 2.
I have designed an 8 bit sar ADC using Cadence virtuoso. I have designed the layout of the comparator and DAC and extracted the parasitic components. What are the methods by which i can reduce the parasitic components?
dear friends I'm working on sar reduction subject and I want to reduce the sar parameter in an antenna project. As you know, because the sar is proportional to the Electric field in order to adjust the sar I can distribute Electric field uniformly and correctly, so how can I adjust the Electric field (...)
Hi all, I am working on 12 bit sar adc,how to simulate the hold time? Thanks Bhanu
Hi All, I have designed a 8 bit sar ADC. (1 LSB ~ 10 mV) In order to test my DNL and INL, I have an outomatic system with ramp input. (The input resolution is ~ 2mV - in order to reduce estimation errors) My typical DNL is ~+/- 0.1 LSB and INL ~ +/- 0.2 LSB. Every ADC has a transition noise with an associated transition region. Due
Hi dear freinds, Can any one please send me the following articles: 1) Hsi-Tseng Chou Jin-Song Wang Da-Jen Wu "Applications of shielding techniques to reduce sar induction in human head" published in Antennas and Propagation Society International Symposium, 2003.

I would like to know how the synthesized aperture would look like if a dish antenna is used for the syntheic aperture radar? How do we determine azimuth resolution of sar in the case of a dish antenna? Is it possible to electronically reduce the effective size of the antenna?
Dear all : In my technology, about 50fF unit cap can achieve 10 bit resolution for CDAC type sar ADC. Now if I use split cap to reduce total capacitance, the result is bad. Does anyone know what the effect for using split cap array ? How large unit cap shoud I use ? thx~~
A well-distributed near-field radiation can reduce the sar. Sometimes (if the mechanical design allows this) increasing the distance between antenna and human body model (only 1mm or 2 mm) helps to pass sar requirements.
Some FCC Test reports on FHSS digital phone has been posted in USA FCC Website, you can search the sar (Specific Absorption Rate) report if you know the model (FCC ID). Panasonic phone will do test requirement.
