The detector readout and trigger are optimized to run at nominal instantaneous luminosity ~2×10 32 cm -2 s -1 . An upgrade which will enhance the experiment's sensitivity by at least an order of magnitude is critical to the completion of LHCb's physics program. This will be achieved by being able to cope with luminosity up to 2×10 33 cm -2 s -1 , and by an improvement of the hadron trigger. In order to achieve these goals, all detector elements will need new front end electronics featuring 40 MHz readout. In addition a new design of the vertex detector (VELO) is critical to the upgrade, suitable to fast and efficient pattern recognition and capable of withstanding the radiation fluence corresponding to 100 fb -1 data taking. The VELO upgrade investigations have focused on pixel solution with readout ASICs that will be developed based on the Timepix readout chip. Other solutions are also under investigation. We summarize a conceptual design of the upgraded vertex detector for LHCb and some of the planned R&D activities.
