Abstract

VERITAS 2.3 is a further step in the development of the VERITAS (VErsatile Readout based on Integrated Trapezoidal Analog Shapers) ReadOut Integrated Circuit (ROIC) architecture designed for high-speed, lownoise readout of the DEPFET detectors in the Wide Field Imager on ESA’s ATHENA X-ray satellite. The chip includes 64 channels, delivering a short processing time of 2.5 μs per readout while targeting a system noise of 3 e⁻ ENC RMS, enabling nearly Fano-limited spectroscopic performance. While the new chip still uses previous versions’ proven 0.35 μm CMOS technology node, we have employed new foundry and process options for better manufacturability and improved reliability. An overview of the design and development of VERITAS 2.3 is presented, along with the first standalone functionality and performance measurements conducted using a dedicated ASIC test setup.
