This report describes a compact logarithmic amplifier using a semi-conductor as the logarithmic element. Very high writing speeds are obtainable with this instrument, which may therefore be used ...

A regular Hack A Day reader sent in a tip about an LM386 stero amplifier with digital volume control. The resulting build is very professional and could easily be adapted into a slick iPod dock bui… ...

A Logarithmic Current Mode Amplifier (LGCMA) is designed and verified by 0.5 μm process aiming at electrochemical signal detection in the miniaturized polymerase chain reaction (μPCR) chip for the ...

A novel architecture of a CMOS image sensor dedicated to improve the output voltage swing of a simple logarithmic sensor, while conserving the simplicity and then the minimized area of the normal ...
