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.
