Abstract: Various embodiments of the present technology may comprise a method and apparatus for a polarizing filter. The polarizing filter may be formed such that the filter has varying polarization axes for blocking reflected light emitted from various directions. The method and apparatus may utilize metal wires or molecular chains to form curved lines across the filter, where the curved lines define the polarization axes.
Abstract: An RF detector (15) is formed to compress the output voltage at two different rates depending on the value of the output voltage. Using two different rates of compression reduces saturation of the output voltage and reduces distortion. The RF detector (15) also provides temperature compensation in the output voltage to reduce output voltage variations due to temperature changes.
Abstract: In one embodiment, a semiconductor device is formed in a body of semiconductor material. The semiconductor device includes a charge compensating trench formed in proximity to active portions of the device. The charge compensating trench includes a trench filled with various layers of semiconductor material including opposite conductivity type layers.
