HERA-B is a fixed target experiment at the HERA proton storage ring dedicated to examine CP-violation in the B-Meson system. Based on the RD20-FElix concept a readout chip has been designed in AMS’s 0.8 μm CMOS process for the HERA-B silicon vertex and inner tracker (MSGC) detectors. Various test chips have been submitted and successfully tested since ’95, thus enabling the submission of a fully integrated 128 channel version in April ’97. Design features of this chip (HELIX128S-2) and test results of its predecessor HELIX128 are presented.
