High readout speed pixel chip developemnt at Fermilab

Pixel detectors are becoming a very important part of high energy physics experiments, including those at the Tevatron and the LHC. At Fermilab, a pixel detector for the BTeV experiment is proposed for installation a few millimetres from the beam. Its information will be used in on-line track finding for the lowest level trigger system. This application requires pixel chips with high readout speed. The architecture of the pixel chips being designed at Fermilab will be presented, and future proposed developments and simulations will be summarised
