Low Noise CMOS Analog Front-End Circuit With an 8-bit 1-MS/s ADC for Silicon Sensors for Space Applications

Résumé

A low-power analog front-end circuit for silicon (Si) detectors has been fabricated in 0.35- μm CMOS technology. It has been designed to readout signals from large-capacitance Si detectors for incident electron energy ranging from 50 to 725 keV. In order to quantify electron energy, the front-end integrates a charge preamplifier, a pulse shaper, a peak detector, and an event-driven analog-to-digital converter (ADC). The complete front end, including the ADC dissipates 2.5 mW for a maximum electron detecting rate of 650 kHz. The charge-to-voltage gain is 60 mV/fC for a charge range of 0.6 to 32 fF. The measured equivalent noise charge is 3119 e- for a 40-pF detector parasitic capacitance.
