GEMINI is a readout ASIC dedicated to the Triple-GEM detector. Fabricated in CMOS 180 nm technology, GEMINI pushes towards the state-of-the-art for this peculiar detector front-end, as regards the count rate and detector pixel parasitic capacitance sustainability.

Abstract

GEMINI is a readout ASIC dedicated to the Triple-GEM detector. Fabricated in CMOS 180 nm technology, GEMINI pushes towards the state-of-the-art for this peculiar detector front-end, as regards the count rate and detector pixel parasitic capacitance sustainability. It features 16 channels, each one including a charge-sensitive preamplifier, an event discriminator with channel-independent threshold and an event-triggered reset. An embedded automatic calibration unit compensates performance for environmental, CMOS process and supply voltage variations. GEMINI sustains a 5Mcps count rate, managing up to 40 pF GEM detector capacitance and consuming 2.7mW/ch.
