Abstract :
A charge preamplifier which has been developed for the warm-liquid calorimeter experiments in the Superconducting Super Collider (SSC) is presented. The amplifier has been designed for implementation in a Harris dielectrically isolated, radiation-hardened, very-high-frequency BiFET IC technology. SPICE simulations after 3 Mrd of gamma ray and 3×1014/cm2 of neutron exposure show that the amplifier has high gain (0.5 V/1 pC), high speed (10-ns rise time), low noise (~378 electrons RMS), and low power consumption (<49 mW). Some of the design considerations and performances are discussed
