  • MONOLITHIC SILICON-BASED PHOTONIC RECEIVER
    Publication number: 20080054391
    Abstract: An integrated circuit, and method for manufacturing the integrated circuit, where the integrated circuit can include a phototransistor comprising a base having a SiGe base layer of a predetermined germanium composition and a thickness of more than 65 nm and less than about 90 nm. The integrated circuit can further include a transimpedance amplifier (TIA) receiving an output from the phototransistor. The phototransistor and the TIA can be built on a silicon substrate.

  • CURRENT SOURCE CIRCUIT AND DESIGN METHODOLOGY
    Publication number: 20070262795
    Abstract: A method of designing a current source involves selecting an equation for a current output through a circuit. Variations in current are checked to make sure they are not a strong function of process and bias. A circuit topology is then created as a function of the equation. Example circuits include an addition based current source and a square root based current source.
