Abstract
The design of the analog front-end of the STS/MUCH-XYTER2 ASIC, a full-size prototype chip for the Silicon Tracking System (STS, based on double-sided silicon strip sensors) and Muon Chamber (MUCH, based on gas sensors) detectors is presented. The ASIC contains 128 charge processing channels, each built of a charge sensitive amplifier, a polarity selection circuit and two pulse shaping amplifiers forming two parallel signal paths. The first path is used for timing measurement with a fast discriminator. The second path allows low-noise amplitude measurement with a 5-bit continuous-time flash ADC. Different operating conditions and constraints posed by two target detectors' applications require front-end electronics flexibility to meet extended system-wise requirements. The presented circuit implements switchable shaper peaking time, gain switching and trimming, input amplifier pulsed reset circuit, fail-safe measures. The power consumption is scalable (for the STS and the MUCH modes), but limited to 10 mW/channel.
