  • Apparatus and method for visible imaging using Darlington phototransistors
    Publication number: 20060076646
    Abstract: The present invention is a modified darlington phototransistor wherein a phototransistor is coupled to a Bipolar Junction Transistor (BJT). This design provides a high sensitivity and a fast response and effectively increases the gain of the photocurrent. This circuit is particularly will suited for the readily available CMOS and Bipolar Complementary Metal Oxide Semiconductor (BiCMOS) processes prevalent today.
