Extremely high radiation background (up to 5 MRad over a 10 year lifetime), a large number of channels (3.2 M), high speed, low noise requirements (1250 electrons RMS), and low power consumption (1 mW/channel), present a formidable challenge for front-end electronics for the Silicon Tracker subsystem for the GEM (Gamma, Electron, Muon) Detector of the Superconducting Super Collider Project. The design requirements and preliminary results from the bipolar designs for an analog integrated circuit are presented. The analog processing chain includes a preamplifier, an amplifier /shaper/baseline restorer combination, and a level discriminator with a logic output.
