1. INTRODUCTION We developed an integrated circuit (IC) for the readout of LAr (Liquid Argon) TPC (Time Projection Chamber) neutrino detectors. These detectors employ LAr simultaneously as massive target and detection medium. The detection of secondary particles produced in neutrino interactions is achieved by collecting, on a system of wires at the sides of the detector, the electric charges f...

This study proposes a chemoresistive gas sensor readout integrated circuit (ROIC) with simple and effective scheme for tracking canceling the offset value. Before reading out sensor, proposed ROIC dynamically updates of analog-to-digital (A/D) reference range suitable to offset, enabling accurate A/D conversion within sensor’s dynamic (DR). Therefore, this approach eliminates need additional co...
