High-gain and high-speed amplifiers are vital in analog circuits. Low-voltage design limits the structure of the amplifiers to change from cascode to cascade configuration. In addition, the stability as well as the bandwidth of the cascaded amplifiers are constrained by the existing frequency comp.....

This invention discloses an alternative approach of electrically tuning silicon-based waveguide-coupled microresonators that employs photoaligned liquid crystals as cladding layers. Planar optical microresonators that partially confine light and support sharp optical resonances have long been demon.....

Field emission displays (FEDs) have been known for a number of years as an alternative to active matrix liquid crystal displays (AMLCDs). Indeed, FEDs are known to have a number of advantages. They can be made thinner and lighter while having better operating characteristics compared to an AMLCD. In.....
