20090270953 | Optical Device - A reflectance-type optical sensor includes one or more photodiodes formed in a semiconductor substrate. A well having sidewalls and a bottom is formed in the top surface of the substrate, and a reflective layer is formed on the sidewalls and bottom. A light-emitting diode (LED) is mounted in the well, so that light emitted laterally and rearwardly from the LED strikes the sidewalls or bottom and is redirected in a direction generally perpendicular to the top surface of the substrate. The optical sensor can be fabricated using microelectromechanical systems (MEMS) fabrication techniques. | 10-29-2009 |
20100165709 | ROBUST SRAM MEMORY CELL CAPACITOR PLATE VOLTAGE GENERATOR - An SRAM having two capacitors connected in series between respective bit storage nodes of each memory cell. The two inverters of the memory cell are powered by a positive voltage and a low voltage. The two capacitors are connected to each other at a common node. A leakage current generator is coupled to the common node. The leakage current generator supplies to the common node a leakage current to maintain a voltage which is approximately halfway between the voltages of the high and low SRAM supplies. | 07-01-2010 |
