20090009154 | WIDE-BAND ANTENNA COUPLED SPECTROMETER USING CMOS TRANSISTOR - To create a broad band spectrometer, a plurality of individual antenna based bolometers are fabricated on the surface of a single spectrometer chip, each bolometer having an individual antenna which is sized differently from all others, thus being responsive to a generally unique frequency of radiation. Each antenna is coupled to a related transistor, which is easily formed using CMOS technology. The antennas are connected to opposite sides of a transistor gate, thus creating a termination resistor for the particular antenna. Multiple outputs from the various antennas are then coupled, thus providing responsiveness to electromagnetic radiation of a very broad spectrum. | 01-08-2009 |
20090243702 | VARACTOR BANK SWITCHING BASED ON NEGATIVE CONTROL VOLTAGE GENERATION - A method and apparatus for varactor bank switching for a voltage controlled oscillator is disclosed.
