Electronics Working Group Results ================================= Tsingua ------- * Single-ch preamp CMOS ASIC, 3x3 mm (could be smaller) * Tests of ASIC with high-quality detector(s) in collaboration with Canberra * Include differential output in next version * Production: Multi-project wafer run, 350 nm process * Already developing a switched capacitor array (currently for GEM readout ASIC) MPP --- * Collaboration with Tsinhua on multi-channel preamp ASIC tests * Will contacs IDEAS (Norway) about noise, cryogenic conditions, and dynamic range KIT (M. Kleifges) ----------------- * Long-term interest in low-power digitization for Auger-like experiments * Eureca: Candidate for Ge instrumentation with new technologies (e.g. ASIC preamps, switched-capacitor array digitization) Analog Input Stage Design ------------------------- * Investigate analog differentiation in preamp to lower dynamic range requirements (calulations by David Radford)
