The Origami Chip-on-Sensor Concept for Low-Mass Readout of Double-Sided Silicon Detectors [article]

M Friedl, C Irmler, M Pernicka
Modern front-end amplifiers for silicon strip detectors offer fast shaping but consequently are susceptible to input capacitance which is the main contribution to the noise figure. Hence, the amplifier must be close to the sensor which is not an issue at LHC, but a major concern at material budget sensitive experiments such as Belle or the ILC detector. We present a design of a silicon detector module with double-sided readout where thinned front-end chips are aligned on one side of the sensor
