Title: Fast BICMOS active-pixel sensor cell with fast NPN emitter-follower readout

Abstract: A read out circuit is provided. The read out circuit includes an emitterfollower circuit (EFC) that receives information indicative of anintensity of light detected by a pixel of an active pixel sensor array.The EFC drives a value related to the information to a read out devicewhen the pixel is accessed.
